The shell hangs as you described on "make world" when the PID
hits 32768.  Looks like this was the old limit and things changed
around release 3.

I went to recompile the kernel with "define PID_MAX 30000" in
/usr/src/sys/sys/proc.h and got a new build error that I'm still
trying to resolve:

     In file included from /usr/src/sys/sys/buf.h:258,
                 from /usr/src/sys/i386/i386/genassym.c:47:

     /usr/src/sys/sys/proc.h:670: error: expected '=', ',', ';',
     'asm' or '__attribute__' before 'PID_MAX'

     /usr/src/sys/sys/proc.h:769: warning data definition has no
     type or storage class

     /usr/src/sys/sys/proc.h:769: warning: type defaults to 'int'
     in declaration of 'pidhashtbl'

     *** Error code 1

Line 670 in proc.h is the define PID_MAX line.  I have the
feeling I may be missing something obvious here, but I haven't
been able to sort out the problem.
