Are there any objections to enable multiple sessions
(one per mapset) in 5.7? Basically:
cp $HOME/.grassrc57 /tmp/grass57-$USER/gisrc.$$
set GISDBASE, LOCATION_NAME, MAPSET
check $LOCATION/.gislock
run GRASS session
rm -f $LOCATION/.gislock
cp /tmp/grass57-$USER/gisrc.$$ $HOME/.grassrc57
rm -f /tmp/grass57-$USER/gisrc.$$
Suggested patch is attached.

There is one set of monitors per user, but monitors are tied to the
session in which they are started due to the redraw-on-resize code
(any commands will be run with $GISRC set to the value which the
driver inherited from mon.start).
I think that we would really need to have one set of monitors per
session. Either that, or just remove the redraw-on-resize code (which
would be a good thing in any case).

So, change _get_make_sock_path() (lib/gis/unix_socks.c) to return
/tmp/grass'VERSION_MAJOR''VERSION_MINOR'-$USER-$GIS_LOCK
instead of
/tmp/grass'VERSION_MAJOR''VERSION_MINOR'-$USER
set $GISRC to tmp/grass57-$USER-$GIS_LOCK/gisrc
and close all running monitors when GRASS session is closed.
Patches attached.
