Modified files:
sys/kern kern_descrip.c
Log:
fcntl(.., F_SETFL, ..) should only do an FIOASYNC ioctl if the FASYNC
bit has changed. Otherwise a program just trying to set O_NONBLOCK might
get an error from devices that don't like FIOASYNC.
The 'pty' device master will fail on FIOASYNC if the slave has not been
opened. This bug caused rxvt to hang, but rxvt only set O_NONBLOCK and
wasn't really at fault.
