[GRASS5] session within a session

I was just able to start a grass57 session from within another grass57
session by mistake (different location). I had thought there was a check
to see if GRASS was already running?

The check has been removed; you are supposed to be able to run
multiple sessions now.

Each session now has its own $GISRC and its own /tmp subdirectory for
monitor sockets.

Ok, the problem remains though: you shouldn't be able to start one GRASS
session from within another GRASS session causing a confused state.

ie test for $GISBASE in current shell during startup, not for any
existing .gislock like files?

Running multiple sessions in parallel is ok, running multiple sessions
in serial is bad.
