On the Apollos, due to high overhead of fork(), you can tell the shells to
not fork when they exec() other processes (don't ask me how the shell gets
back).  In csh/BSD you can do 'set inprocess' to get this behavior.  The
default behavior is normal.

Remember, Apollos don't run UNIX(tm) or even Unix(which we all know and love),
they run AEGIS(which has everyone confused).
