          the callback when both happen concurrently, instead of giving
          one precedence.
        - install C library documentation as EV::libev manpage (sorry, oesi).

        - (libev) work around another bug in windows perls and
           windows itself: failed connects do NOT set read or write

          reference, for earlier error reporting and a nice calling
          speed increase (as well as saving memory).

          select on windows when not waiting for any file descriptors.

167			darwin and openbsd and thus almost everywhere.
168			- add some allowance in t/01_timer.t for the uneven monotonic
169			vs. realtime clock tick on at least freebsd.
170			- add -lsocket -lnsl on solaris in case the perl guy forgot to
171			configure them.
