Arnaldo Carvalho de Melo 082ab9a18e perf trace: Filter out 'sshd' in the tracer ancestry in syswide tracing
Avoiding a loop, so now its quite convenient to ssh to a machine and
then simply do:

	# perf trace

To trace all syscalls without causing a loop.

This was possible using --filter-pids, i.e. once you noticed the loop,
get the sshd pid and add it to --filter-pids, restarting the 'perf
trace'.

Now to figure out how to do that in a X terminal, the other common
scenario, which is way more involved, as there are multiple processes
communicating to process terminal activity...

Using --filter-pids + '-e \!syscall,names,you,dont,need' may be a good
approximation when having to do syswide tracing on your workstation.
