close-on-exec handles are left open by exec parent

[egor duda]

Hi!

  here's the proposed patch. it also contains a fix FreeConsole ()
related bug -- when cygwin application frees its console,
"process_input" thread may be still running. When console is closed,
WaitForMultipleObjects () with console handle returns WAIT_FAILED, so
"process_input" thread starts cycling and eating CPU.
