CVS commit: src/tests/fs/vfs
Module Name: src
Committed By: pooka

Add a kludge to prevent a test run from completely hanging.
1) p2k_ffs test program opens a socketpair and forks off rump_ffs
2) after mounting the file system, test program decides it
wants to skip the test and exits
3) somehow, the puffs event thread of rump_ffs stays in kqueue
waiting for activity. fstat+gdb suggests it's waiting for the
now-orphaned socketpair (but I didn't fully verify. is there
an easy way to dump the state of a kqueue descriptor?).
4) test program is a zombie
5) atf-run waits forever
Note: this doesn't trigger always.
So, it seems there are at least two bugs: 1) test case doesn't
timeout 2) the kevent call in rump_ffs never returns even though
the sockerpair is orphaned
So, explicitly unmount the file system before skipping the test.
Obviously the above bugs needs to be properly fixed, since other
skipping test cases can unbeknowingly trigger the issue.
