	instead of MADV_DONTNEED on Linux when returning memory to the
	kernel. This is more efficient, but means RSS numbers will
	drop only when the OS is under memory pressure. On the BSDs and
	Illumos/Solaris, setting madvdontneed=1 will use MADV_DONTNEED instead
	of MADV_FREE. This is less efficient, but causes RSS numbers to drop
	more quickly.
