system semi-freezes on mbuf cluster limit

I just experienced a nasty situation: I ran out of mbuf clusters (6656) and ppp was one of the processes stuck in objcache_get.

even after some clusters drained (from netstat -m output), the objcache depot didn't get free entries back and ppp stayed stuck. and of course because of this no mbuf clusters were freed (ppp would have to transmit them, i guess). I was doing some serious down/uploading at the moment.

this should not happen, or at least more gracefully.

cheers
 simon
