problem with readonly pinfo?

If I as a process group leader fork/exec a process, it doesn't seem like
there's any way to distribute signals to the suid'ed subprocess since
the shared memory region (or eventually pipe) for the subprocess will be
inaccessible.

Is there a way to play around with the security descriptor to fake process
groups?  Also, isn't the owner of a process always allowed to send the process
a control-C even if the owner is different than the uid of the process being
run?
