I'm not claiming there isn't a problem. I'm claiming that whatever problem=20
exists is not preallocs that are not being discarded because of the=20
truncate optimization.

afs holds one file open: the CacheItems file (on bsd's, it holds two files=20
open: the CacheItems file and the VolumeItems file). That's it. other calls =

to afs_CFileOpen/afs_CFileClose are balanced

% xstat_cm_test localhost -once 0 | egrep 'osi_UFSOpen|osi_Close'
            344299 osi_UFSOpen
            344298 osi_Close
