SVN rev 216793 on 2010-12-29 11:39:15Z by kib
Add sysctl vm.md_malloc_wait, non-zero value of which switches malloc-backed
md(4) to using M_WAITOK malloc calls.
M_NOWAITOK allocations may fail when enough memory could be freed, but not
immediately. E.g. SU UFS becomes quite unhappy when metadata write return
error, that would happen for failed malloc() call.
