I wonder why it behaves more or less good under Unix). I don't know what you mean by a "busy loop" but I haven't heard any reports that select works less than reliably.

FWIW, gdb uses both with no problems. cgf -- Want to unsubscribe from this list? Send a message to cygwin-unsubscribe@sourceware.cygnus.com
