1.7.19 backtrace

I saw the bug again with Wine 1.7.19. A backtrace is attached. I have a core
dump and a corresponding wineserver binary, but they are too big to attach
here.

My suspicion is that the backtrace is slighly off, and that the crash happens
in fd_reselect_async rather than async_reselect, and that the cause is either
an undefined async object or one that does not define fd_ops->reselect_async.
I'll add some more debug output to my code and hopefully remember to run with
WINEDEBUG=server next time I play WC3 multiplayer.
