dmake on SysV with -Pn

[Leslie Mikesell]

Is the dmake program supposed to work with multiple processes
under SysV?  I had no trouble compiling under SysVr3.2 (AT&T - 386)
but if I specify -P number it never seems to complete.  Sometimes
it will finish the operations but the last process never exits.
Have I missed something obvious or is this not supposed to work?
