Because that id is used to determine the id of the printer memory
segment for the process. If you have two UV processes with the same
gpid, they end up sharing the memory segment. This is where your
MFILE structures are stored (rotating file pool), among other things.
Pointers get mixed up, and you end up getting some files data written
into a completely different file, usually corrupting the group or
even the file header, depending on how angry the computer gods are
that day.
