Quoth roy@alanine.phri.nyu.edu (Roy Smith) (in <1991Apr12.185019.20329@phri.nyu.edu>):
#
#	Sometimes, when I'm working on multiple clients of the same NFS
#server at the same time, I'll do something on one and not see it on the
#other for a while.  This is obviously because of NFS caching and can by
#annoying.  Is there any simple way to force all the NFS caches to get
#flushed, like sync does for the ufs caches?

Not as such. However if you're prepared to take a slight performance
hit (hah!) you can tweak the behaviour in the way you want,
using the acXXX mount options. (See "man mount" for details.)
If you set "noac" you can run in an essentially synchronous
mode.
