        I have an old application that I will eventually convert from GL to
Performer. What I tried to to as a quick fix is to make it two processes,
app and draw (I used sproc.) This worked most of the time. After a
random amount of time the graphics pipeline (RE2) would crash. I am not doing
any GL calls in the app. I think the problem was that the app could be
writing to data (like a matrix) while the draw was accessing it (like
multmatrix). Can that be a problem? How does perfromer handle this?
Does fork and shared memory fix the problem or does Performer make a copy
of the data before making a GL call?

Thanks in advance.
