Hello, everyone.

I tested the latest snapshot of cygwin1.dll, and
noticed that vim editor respond too slow on it.

When I open some file with vim, the text appears
after a few seconds. ^F and ^B keys also update
the screen very slowly.

I tried to bisect the problem, and found that this
problem occurs after :

commit e5665d8c930485d5ac6d8913573e27b9e5043d92
Author: John Hood <cgull AT glup DOT org>

    Improve and simplify select().

    * select.h: Eliminate redundant select_stuff::select_loop state.
    * select.cc (select): Eliminate redundant
      select_stuff::select_loop state.  Eliminate redundant code for
      zero timeout.  Do not return early on early timer return.
      (select_stuff::wait): Eliminate redundant
      select_stuff::select_loop state.

I hope this problem will be fixed before release.
