increasing MAXNFSDCNT

Regarding the maximum number of nfs server threads, is increasing the
"#define MAXNFSDCNT 256" in nfsd.c the only thing needed to try higher
values?

My FreeBSD nfs servers are still just at 128 threads, but I was
experimenting with one of our linux servers which became happy
at 512 threads (really ~400 in use under load). The load profile is
pretty similar, so it might be reasonable to expect ending up around the
same value.
