Fun fact: since the server daemonizes into its own process group,
it's not in atf's pgrp. Use rump_sys_reboot() in atf cleanup to
kill the server after the test.
* RUMP_MEMLIMIT works
* allocating memory with PR_NOWAIT will fail immediately if no memory
is available and PR_WAITOK will wait for memory to be available
the LDADD variable expansion. To support static linking, ensure
that the common libraries gets tacked on at the end as well (order
matters for static linking), by using a convenience variable and
add it to the end of LDADD.t_modlinkset, as well as when doing the
general LDADD+= setting.
this becomes apparent when linking statically (e.g. as for sun2).
Add an extra instance of -lrump to the library list so that it can be
linked statically as well.
