	also means that any allocator set as the default needs to be ready to
	deal with arbitrary memory allocation requests; in addition, the size
	and number of requests will change between releases.

	An allocator set as the default will never be released, even if later
	another allocator replaces it as the default. Not only is it impractical
	for it to be released (as there might be caches created under the covers
	that refer to the allocator), in general it's also safer and more
	efficient to keep it around.

	If you wish to use a custom allocator in a context, it's best to provide
	it as the argument to the various creation functions rather than setting
	it as the default. Setting the default allocator is not encouraged.

	If you do set an allocator as the default, either do it for all time in
	your app, or do it in a nested fashion (by restoring the previous allocator
	when you exit your context). The latter might be appropriate for plug-ins
	or libraries that wish to set the default allocator.
