Try the sourceforge patch tracker at

Neat stuff.

The expectation for regress.exe on windows is that it pass with no
errors. (FWIW, the --no-fork option is only for debugging and
internal use; using it with more than one test at a time is likely not
to work.)

Weirdly, it works on mingw, which is why I hadn't noticed it. [I
guess this is what happens from not having a working MSVC build.] But
yeah, that should be a send, not a write. I've just fixed that in
the repository.

Heh. Unless somebody volunteers to rewrite all of *my*
currently-working code that was written to use the existing APIs, I
will sure find it unpalatable to break them. I suspect that other
people who have written applications with the current Libevent will
feel the same way.
If there's something that really sucks in a current interface, the
right approach is probably to add a _new_ API that can do the right
thing, while we deprecate the old API but keep it working. That's
what we did with event_set() in 2.0.1.
