Try to figure out what happens inside w32proc.c:sys_select would be a
beginning, I think.  There are already quite a few DebPrint statements
in that function; compiling with EMACSDEBUG defined will activate
them.  You should be able to see the strings emitted by DebPrint with
any debugger; or you can install DbgView as a lightweight solution.

Once you have this in place, add DebPrint as needed to see what is
going on there.
