It's safe, yes. Offlineimap handles per-account locks. However, I didn't
check if the lock is released after a refresh sync or when the refresh
run is stopped.

I guess most of the users open a terminal to manually start a run, yes.

With refresh mode, you can send a SIGUSR1 to start a full sync. See the
SIGNAL section of the manual.
