	deal with arbitrary memory allocation requests; in addition, the size

	An allocator set as the default will never be released, even if later

	for it to be released (as there might be caches created under the covers

	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
