new approach to calling fork(2) in remote Lisp images
Drop CAN-PROBABLY-FORK because we now only try to fork(2) in contexts in which
there shouldn't ever be any other threads running, apart from Lisp
implementation finaliser threads and the like.
We no longer need to RESET-DATA-SOURCES before CONTINUE-DEPLOY* because we now
only fork(2) in contexts in which *NO-DATA-SOURCES* is t.
