ptrace in unix tracing non-child processes

[Narayan Mohanram]

Has any one considered implementing a `xptrace ()' which can 
debug non-child processes. This will get one the ability to
debug processes such as daemons that are already running.

eg:

	debug -p pid

Then background processes and demon processes that have no
relationship to the debugger can be debugged.
