Problem: When a timer uses ":pyeval" or another Python command and it happens to be triggered while exiting a Crash may happen. (Ricky Zhou) Solution: Avoid running a Python command after python_end() was called. Do not trigger timers while exiting. (closes #1824)

#! /bin/sh
#
# which.sh -- find where an executable is located.  It's here because the
# "which" command is not supported everywhere.  Used by Makefile.
