In the general case, you can increase the size of the mutex pool. However,
since this is per-uid for the socket buffer resource limits, that won't help
you as the same user will always contend with itself. We'll need to think
about this some -- good activity for the plane today :-).
Nice work so far, btw. Sounds like we're making real headway!

int
chgsbsize(uip, hiwat, to, max)
struct uidinfo *uip;
u_int *hiwat;
u_int to;
rlim_t max;
{
rlim_t new;
UIDINFO_LOCK(uip);
So the next question is how can that be optimized?
