.sherpa-session-<pid> created in home directory

If you use Sherpa in S-lang scripts, your home directory will be filled with .sherpa-session-<pid> files. (These files are only supposed to be created when Sherpa exits with a nonzero status.) These files do not interfere with the operation of Sherpa, but do create a lot of clutter.

Workaround:

you can stop this by explicitly ending the slsh script or chips session by calling sherpa_eval("exit").

Importing the sherpa module into an slsh script causes the script to hang at exit, forcing the user to kill it with Ctrl-C.
