Description

This change causes problems:
'make -j4 buildworld' fails, seemingly random, eg. as below.
this is with /usr/src and /usr/obj nfs mounted; nfs server running dfly 1.8.2.

After make failed, executing 'mv _clear_cache.o.tmp _clear_cache.o' succeded.

- vfs.nfs.pos_cache_timeout=0 doesn't help.
 - 'make -j1 buildworld' succeeds.
 - using ufs for /usr/obj makes -j4 work.
 - backing change in commit out (and using nfs for /usr/obj) makes -j4 work.
-thomas
- 'make -j4 buildworld' with /usr/obj nfs mounted

I figured it out, and reproduced it.  The issue is that the underlying
    vnode being disassociated from the namecache topology has to be 
    synchronized with the NFS server or the next lookup of the filename
    may get stale information.  In this case, the file permissions for
    the newly created file had not yet been synchronized with the server.
I'm working on a fix.  In the mean time, just set the timeout to
    around a minute (the 30-second filesystem flush will resynchronize
    the client and server so a cache timeout of 60 seconds ought to do
    the trick).

I've committed /usr/src/sys/kern/vfs_cache.c rev 1.83 and I believe
it will fix the problem. Please sync up with change and tell me if
you still have the problem!
