quote from md(4):
malloc Backing store is allocated using malloc(9). Only one malloc-
bucket is used, which means that all md devices with malloc
backing must share the malloc-per-bucket-quota. The exact size
of this quota varies, in particular with the amount of RAM in
the system. The exact value can be determined with vmstat(8).
