From the Vinum intro:

"In order to perform its functionality, Vinum allocates a large
 number of dynamic data structures. Currently these structures are
 allocated by calling kernel malloc. This is a potential problem,
 since malloc interacts with the virtual memory system and may
 trigger a page fault. The potential for a deadlock exists if the
 page fault requires a transfer to a Vinum volume. It is probable
 that Vinum will modify its allocation strategy by reserving a small
 number of buffers when it starts and using these if a malloc request
 fails."

Has this "potential problem" been addressed in the Vinum in Stable?

If not, is there any other way to prevent a system panic if a drive 
containing a swap partition fails?
