Stability hack.  Under Solaris when KM_SLEEP is set kmem_cache_alloc()
may not fail.  To get this behavior I'd added a retry to the shim layer
even though it is abusive to the VM, at least it should prevent the crash.
Additionally I added a proc counter so I can easily check how often this
is happening.  It should be fairly rare, but likely will get worse and
worse the longer the machine has been up.
