Description

A lock is required so two gump processes do not run at the same time, and conflict. The mechanism employed today is flawed in that the OS can not clean up the lock on process termination, so we get stray locks left around.

P.S. Eventually we ought lock the workspace, and ensure that two workspaces can run simultaneously. Right now even that is not true, with use fo $GUMP/tmp.
