David Wilson 01729b18a5 core: use an output deque rather than string to improve worst case perf
This probably worsens performance in the common case, but it prevents
runaway producers (see e.g. issue #36) from spending all their CPU
copying around huge strings.

It's also a small step towards a solution to issue #6, which will
replace the output buffer with some sort of fancier queue anyway.

This reduces a particular 40 second run of rsync to 1.5 seconds.

David Wilson fb9ce1054c core: set O_NONBLOCK on every side. Closes #33
The last time I tested set_nonblock() as a fix for the rsync hang, I
used F_SETFD rather than F_SETFL, which resulted in no error, but also
did not set O_NONBLOCK. Turns out missing O_NONBLOCK was the problem.

The rsync hang was due to every context blocking in os.write() waiting
for either a parent or child buffer to empty, which was exacerbated by
rsync's own pipelining, that allows writes from both sides to proceed
even while reads aren't progressing. The hang was due to os.write() on a
blocking fd blocking until buffer space is available to complete the
write. Partial writes are only supported when O_NONBLOCK is enabled.

David Wilson e4c832685d core: synchronize Stream._output_buf by deferring send()
Previously _output_buf was racy. This may or may not be cheaper than
simply using a lock, but it requires much less code, so I prefer it for
now.
