- * 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)
