If the lock file is left on the disk because of a program crash,
then trying to delete it on program close might not always work.

On the other hand, deleting a lock file present on the disk
on program startup (or rather: when the user connects to the
mapset) is not a good idea, because that file might be there
for a good reason (e.g. someone else working on the same mapset
over a network connection)!

There needs to be a mechanism to detect whether the GRASS plugin
or QGIS itself have crashed while connected to mapset A. If that is
true, then the GRASS plugin should tell the user, next time he or
she connects to mapset A, that a crash occured in the last session
and offer to remove the lock file.
