Basically, now that I have you on this, I am going to do some more
tests.

The kernel version: 2.4.27 w/libc2.3.2
The shell         : bash v2.05.0(1)
The Dosemu version: 1.3.1 + time patch

user, currently root, but I believe also non-root
going to retest that.

from shell, run a /bin/sh script that runs dosemu in
a while []; do .... done loop

from crond root run a line that touches a 'restart' file in
C:/ and kills -TERM dosemu.bin, exiting to the original shell
while [] loop, the screen is ok (the shell's) but the kbd is
in echo strange characters mode and not passing to the original
shell.  dosemu is not restarted, no way to do a ps to check what
is running.

however, if I switch to a 2nd tty and run top, I see dosemu.bin
being restarted every 10min (for this test) and all is good!

more later
Thanks
TonyB
