	Glad you mentioned it...I am having tremendous trouble with block
size on the NeXT...I planned to use my cube as a fileserver for about 
20 386s running SVR4, but they don't like really big blocks, the sun4
we are using now perfroms great if files are mounted with rsize=1000 and
wsize=1000. Trying this on the next causes stats of a mounted directory 
to fail. (this means that "ls /mntdir" returns no file list). this occurs
even between two NeXTs as well...leaving it at the default causes the 386
to eventually choke on a big block, passing the error "nfs_server: 
bad sendreply" back to the servers console window. setting rsize=2000, causes  
even two nexts to catch fire reporting more bad sendreplys, and
other goodies which cause the client to hang up altogether. I have reported  
this to NeXT, though their first reply was to uncoil my thinet cable (?)

    anybody else have any ideas?
