I successfully added UMS to libuv, it works. See commit

The speed isn't too much slower, see fs_stat.txt
<https://github.com/codepilot/libuv/blob/libuv/ums/test/fs_stat.txt> vs
fs_stat_ums.txt
<https://github.com/codepilot/libuv/blob/libuv/ums/test/fs_stat_ums.txt>
The speed difference is mostly because UMS has some builtin
synchronization, and so does the work queue. These conflict some, but do
not cause errors, just slow downs.
Great work, thanks for sharing!
IMHO, this is not the right way to integrate support for UMS, though
it's a great way to see it working.
I think uv_thread_create should always use native threads. Then Windows
could use a threadpool implementation which uses UMS threads instead of
native threads. Doing this you might be able to simplify synchronization
and thus get some speedups.
