[Users] flashcache

[Aleksandar Ivanisevic]

I am actually planning on using it only on test systems where i have
commodity SATA disks that are getting a bit overwhelmed. I hope to get
better value from a SATA+SSD combination that I would with SAS disks and
the appropriate controllers and fancy RAID levels that cost 3 times
more at least.

Anyway, looks like that bug also got fixed in 092.1, at least it doesn't
oops immediately any more.
