Dave, may I ask you kindly for briefly elaborating on the worst consequences 
of just reverting this hunk, as I've done before?

I've briefly tested this with a codebase somewhere between -rc3 and -rc4, 
and it survived the du test, but it suffered from some strange network drop 
outs, that aren't funny on a nfs server...

Will retest your patches after opensuse-current catched up with -rc4. 
Hopefully, the most blatant stability issues are fixed by then.

Cheers,
Pete
