I'm not sure what you're saying here.  Are you expecting that the OP is
going to "zap" the X server (by which I believe you mean pressing
a magic key combination like Ctrl-Alt-Backspace, with an appropriate
option set in the xorg.conf file to cause that to terminate the X server)
rather than exiting from MATE in the normal manner?

I'm expecting that the OP is exiting/logging out of MATE in whatever
the normal way is.  Further I'm expecting that this normal logout
action causes the "magic MATE start command" to terminate, returning
control to the .xsession script.

We're not "falling out of .xsession" either.  It's just a shell script,
so it works the way any other shell script works.  When the MATE session
ends, the .xsession shell script moves on to the next command, which
is kill.

I know nothing about unison itself.  That might work, but I can't confirm
or deny it.  In either case, it doesn't appear to be what the OP wants.
