Bug#624507: Fwd: also exists in Fedora, explanation

[Daniel Pocock]

I am raising the severity to `serious' because this hammers the NFS
fileserver and causes severe performance degradation for users logged in
with NFS home directories.

Similar issue reported in Fedora, unfixed there too apparently:

   https://bugzilla.redhat.com/show_bug.cgi?id=561904

The explanation at the bottom suggests that it is caused by multiple
processes accessing the redo log concurrently, particularly if there are
multiple NFS clients logged in as the same user presumably.

Various hacks are given in the Fedora bug, e.g. cron jobs to kill the
runaway process, but that is not an ideal fix

I'm observing this problem on squeeze with gvfs 1.6.4-3
