This will make the behavior robuster if many addresses are added
after the size estimation of storage at the first sysctl.

'single threading thread' when the last other thread suspends.
I had this code in there before but it seems to have been
accidentally deleted somewhere along the way. This would only affect
multithreaded processes.

casts are useless under the normal circumstances (and would be harmful
if the functions had no prototypes.)

of the inlines, like its cousin, m_free(). Also, make a small (first
step?) optimisation of m_free() to use the MBP_PERSIST{,ENT} interface
to hold the lock across frees when possible. The thing is that right
now, we can only do this easily for at most across one mbuf + one
cluster free, as the comment mentions (it also explains why). Anyway,
some basic tests revealed a 5-10% overall improvement. Some of the
results can be found here:

o Always check a setsockopt(2) return value
o Use a consistent message format
o Don't abort if the failed setsockopt(2) was actually not vital
o Use LOG_WARNING, not LOG_ERR, in non-fatal cases

a ucred by itself as part of an nfs descriptor, then bzero's the ucred,
fails to initialize the mutex, etc. This is very bad, but I don't have
time to fix it right now. nfsd should instead hold a cred pointer,
and the credential should be properly initialized, probably from a
descendent of a kernel process credential.
