Summary: SunOs has it1

SunOs ptrace() has this facility.  You can give it a pid with
the PTRACE_ATTACH request and attach to another process.  The other
process must be one of "yours" i.e. same uid/gid.  The process gets
a SIGSTOP.  A PTRACE_DETACH is used to send the traced process on
it's way when you've lost interest.

This facility is used by dbx.  You can give it a pid in place of
a core file name e.g. "dbx fnurg 1022".
