That is PII 266MHz with 192MB and Win2k; X-Vision 7.3 + some other apps always
running. On my Unix system (that is MIPS R4400 200MHz with 256MB) I get even
more hashes ... and on home system (PIII 733, 128MB, Mandrake 8+) none at all.

Something has changed in the way zpty runs commands (I fixed the above once
already). Look here:

mw1g017@MW1G17C% zpty zsh /usr/bin/zsh
mw1g017@MW1G17C% ps
      PID    PPID    PGID     WINPID TTY  UID    STIME COMMAND
     1900       1    1900       1900   0 1006 21:17:16 /usr/bin/zsh
     2216    1900    2216       1760   0 1006 21:17:21 /usr/bin/zsh
     3140    2216    3140       3140   1 1006 21:30:23 /usr/bin/zsh
     2412    3140    2412       2696   1 1006 21:30:24 /usr/bin/zsh
     3308    2216    3308       1932   0 1006 21:30:26 /usr/bin/ps

The tty0 is my current and tty1 is pts; when I unload zpty (test does it) it
basically sends HUP to tty group - but we have *two* tty groups here. So the
second zsh is stuck around with Test/comp.tmp as current dir that prevents it
from being removed:

mw1g017@MW1G17C% zmodload -u zsh/zpty
mw1g017@MW1G17C% ps
      PID    PPID    PGID     WINPID TTY  UID    STIME COMMAND
     1900       1    1900       1900   0 1006 21:17:16 /usr/bin/zsh
     2216    1900    2216       1760   0 1006 21:17:21 /usr/bin/zsh
I    2412       1    2412       2696   1 1006 21:30:24 /usr/bin/zsh
     2288    2216    2288       1924   0 1006 21:37:17 /usr/bin/ps
