 So it will only strike on SMP machines. The rump_allserver process does:
 
 #0  0x00000000482094ec in __nanosleep50 () from /usr/lib/libpthread.so.1
 #1  0x0000000048009db0 in rumpuser_nanosleep () from /usr/lib/librumpuser.so.0
 #2  0x0000000047decc80 in rumpns_kpause () from /usr/lib/librump.so.0
 #3  0x0000000047d92894 in rumpns_pserialize_perform ()
    from /usr/lib/librump.so.0
 #4  0x0000000046f20c8c in rumpns_npf_config_reload ()
    from /usr/lib/librumpnet_npf.so.0
 #5  0x0000000046f209ac in rumpns_npf_config_init ()
    from /usr/lib/librumpnet_npf.so.0
 #6  0x0000000046f215a8 in ?? () from /usr/lib/librumpnet_npf.so.0
 #7  0x0000000046f215a8 in ?? () from /usr/lib/librumpnet_npf.so.0
 
 Can we please urgently fix the pserialize vs. rump issue?
 
 This leaves the open question why atf does not timeout - I have not idea
 on that, ktrace shows it dropping out of poll() regularily.
 
 Thanks,
