Log Message:
Change "if (l->l_flag & L_SA_UPCALL)" to "while (l->l_flag & L_SA_UPCALL)"
in userret() functions or equivalent, to permit delivery of multiple upcalls
in a single kernel entry.

XXX It's getting crowded in here. Collapsing posting signals, upcalls, and
XXX kernel-exit handling into one mechanism would be nice.
