* If EAGAIN and/or EWOULDBLOCK are defined, we can't just return -1 in all
* situations where ioctl() does.
*
* On AIX 4.1.5 (and presumably some other versions and OSes), as you
* perform the manual test suite in the README, if you 'bg' vi immediately
* after suspending it, all is well, but if you wait a few seconds,
* usually ioctl() will return -1, which previously caused tty_setty() to
* return -1, causing Rawmode() to return -1, causing Inputl() to return
* 0, causing bgetc() to return -1, causing readc() to set doneinp to 1,
* causing process() to break out of the main loop, causing tcsh to exit
* prematurely.
*
* If ioctl()'s errno is EAGAIN/EWOULDBLOCK ("Resource temporarily
* unavailable"), apparently the tty is being messed with by the OS and we
* need to try again. In my testing, ioctl() was never called more than
* twice in a row.
*
* -- Dan Harkless <dan@wave.eng.uci.edu>
*
* So, I retry all ioctl's in case others happen to fail too (christos)
