Note that at present I think the only way they would have happened not under-lock is if one of the pthread or syscalls failed, which should never happen. Exceptions thrown by the predicate were already always rethrown under lock. But it doesn't hurt to be safe.

And it turns out that the Windows implementation was returning too early due to rounding error. Fixed.

It turns out GetTickCount64() is only precise to the nearest timeslice, which can be up to 16ms. The imprecision caused test failures.

Gotta admit, Win32's modern synchronization interfaces (introduced with Vista) are beautiful.

Once upon a time, POSIX specified that these static initializers could only be used for global variables, but apparently essentially all implementations have always supported these initializers for local variables as well, and POSIX recently enshrined this as a requirement.

I originally left this unimplemented because pthreads annoyingly doesn't support condvar on top of rwlocks. It turns out there's a trick that can be used involving an extra mutex and some redundant locking operations -- the same trick that powers std::condition_variable_any. I used that here.

Win32 support will come in a subsequent commit, before merging to master.

Add OpenBSD to posix_memalign ifdef

Introduce kj::attachVal(), kj::attachRef(), and capnp::clone() utility functions

Add TwoPartyServer::drain().

This is frequently needed. Sandstorm had `OwnCapnp` for this purpose:

https://github.com/sandstorm-io/sandstorm/blob/4d86a8144cdb43120ea12845738d0fe4a6ffcda1/src/sandstorm/util.h#L495-L525

The Workers codebase has some ad-hoc copies of this logic too, and multiple people have requested something similar on the mailing list.

This is a lot like Own<T>::attach() but for the case where you don't have a Own pointer, you just have a reference or value that you want to attach stuff to.

Align HTTP entity-body delimiting rules with RFC 7230.

Skip test that fails under qemu-user, probably due to a qemu bug.

The main case where the code was wrong is when neither Content-Length nor Transfer-Encoding was provided on a response. In this case the response is delimited by closing the connection, but KJ previously rejected it outright. AFAICT almost no one on the whole internet relies on this anymore... almost.

Fix exclusiveJoin() bug when both branches complete simultaneously.

Implement FD passing in Cap'n Proto. 

Fix uninitialized byte arrays in encoding-test.

Initializer lists are temporaries. The code apparently works in debug mode but fails when optimized.

Add support for url-safe base64 encoding

Fix bug in `kj::newOneWayPipe(0)`.

Fix typos spotted by @a-robinson and update test failure messages to indicate that either testing failing could be due to OS SCM_RIGHTS truncation bug.
