New Revision: 296416
URL: https://svnweb.freebsd.org/changeset/base/296416

Log:
  Signal handling within tcsh vfork code path will conflict with some system
  libraries (such as libthr) which maintain their own signal state. This
  change adds the tcsh SAVESIGVEC option to save and restore the sigvecs for
  the signals the child modifies before it execs.
