>Description:

Not sure if this is a kernel, libpthread or rump issue: recently the pppoe
test fail randomly and if failing leave a rump_server around.

Initially I only saw this on a (non-SMP) armv5 system, but now it also happened
on a dual core armv7.

>How-To-Repeat:

Repeatadly run something like:

	cd /usr/tests/net/if_pppoe && atf-run|atf-report
	pgrep rump_server

>Fix:
n/a
