Surely you guys are joking.  I thought everyone had long since replaced their
SunOS "trace" with our very own pk's marvelous "strace", which can do just
that.  The volume of the "YESSSSSS!!!!!!" that emitted from my office when I
watched my first child process get followed by "strace" could be heard
several floors away  :-)

Just in case this helps, I never saw a single one of these on my IPC running
1.0.  Just last Friday I upgraded to a SPARCstation-2 (hallelujah!  I can
actually run an MBONE app w/ a video window now (-: ) and within a few days
I got my first "panic: pmap_page_protect !PG_V 2" crash; sometime during the
night while "xlock" was in control.  Maybe something just afflicting 4/75's?
(Oh, and this still under 1.0, not -current.  Yet.)

One last thing: I'm ordering a Weitek chip upgrade for this new [sic] SS2;
(a) anyone know a good cheap source for them (plus the tool)? (b) once I
have it, and have a chance of rebuilding the world in between sup's, is there
any air-tight set of steps to going from 1.0 to -current?  Should I just
assume that whatever the last set of steps that Alistair posted (I assume
for the i386 port) will work?
