hmm...this never ever happened here and I am currently trying to find out
why.

I attached a test and it seems to be a problem of the -D (ebug) switch.
But I am not sure, because I had not enough time to test.

Start & Restart gpm with killall

flapp:~ # killall gpm
flapp:~ # gpm -v
gpm 1.20.1, Thu Oct  4 00:21:21 CEST 2001
flapp:~ # gpm -t ps2 -m /dev/misc/psaux
flapp:~ # killall gpm
flapp:~ # gpm -t ps2 -m /dev/misc/psaux

--> no problem at all

----------------- snip 1 -----------------------------
Start & Restart gpm with killall in debug mode


flapp:~ # killall gpm
flapp:~ # gpm -t ps2 -m /dev/misc/psaux  -D &
[...]
flapp:~ # killall gpm
*** debug ***: [gpm.c(903)]:
Removing files /var/run/gpm.pid and /dev/gpmctl
[1]+  Done                    gpm -t ps2 -m /dev/misc/psaux -D
flapp:~ # gpm -t ps2 -m /dev/misc/psaux
flapp:~ # ls /dev/gpm* /var/run/gpm*
/dev/gpmctl  /var/run/gpm.pid

--> files are not deleted in debug mode...

----------------- snip 2 -----------------------------
Stop gpm and see what files are left:

flapp:~ # killall gpm
flapp:~ # gpm -m /dev/misc/psaux -t ps2
flapp:~ # ls /dev/gpmctl=20
/dev/gpmctl
flapp:~ # killall gpm
flapp:~ # ls /dev/gpmctl=20
ls: /dev/gpmctl: No such file or directory
flapp:~ # ls /var/run/gpm*
ls: /var/run/gpm*: No such file or directory


--> just fine
