And, perhaps more importantly - can it sleep when called via vfsinit()
from main() ? Some filesystems initialize pools and they currently
don't pass PR_WAITOK. This is sometimes problem - when I load/unload
e.g. msdosfs LKM several times, I get occasional panic in pool initialization
function (I don't recall exactly, but probably pool_page_alloc_nointr()).
