 Priority:  blocker               |   Milestone:

 Test Script:
 {{{
 Thread.start do
   loop do
     begin
       fd = IO.sysopen("/tmp/aaa.txt", "a")
       io = IO.for_fd(fd)
       io.write("aaaa")
       GC.start
     rescue => e
       p "fd = " + fd.inspect
       p "io = " + io.inspect
       raise e
     end
   end
 end.join
 }}}

 Result:
 {{{
 $ DYLD_LIBRARY_PATH=. ./miniruby ~/tmp/test_io.rb
 "fd = 5"
 "io = #<IO:fd 5>"
 /Users/watson/tmp/test_io.rb:6:in `block': Bad file descriptor - write()
 failed (Errno::EBADF)
         from /Users/watson/tmp/test_io.rb:2:in `block'
