I reduced vfs.nfs.maxasyncbio to 16 (from default of 64),
and haven't seen the 'Insufficient sendspace' since.
NFS stall can still be experienced, if I do 'too many' things at once,
e.g. doing `git status' with repo and checkout on NFS mounts while
doing `make -j3 buildworld' did stall NFS.
Forced core dump avail. on request.
Using x86_64 system also still stall NFS (above was i386);
here forced core dump didn't work out, `panic' failed to generate core dump.
