This problem is also in Linux (i686-Linux) according to Xavier's log:

   /usr/lib/ruby/1.8/cgi.rb:725: [BUG] rb_sys_fail() - errno == 0
   ruby 1.8.2 (2004-12-25) [i686-linux]

I hope this gets fixed before some idiot goes around crashing all the 
rubyonrails sites that depend on mod_fastcgi.

ALL:  Please post a 'diff -ruN' patch for the fix just in case an 
updated version isn't released for a while.
