That's very restrictive of course, and means you do not get
page relocalization effects, which can be significant.

Conservative GC is very dubious for any mission critical
software that has to worry about memory leaks. The idea that
any arbitrary object MIGHT fail to be released as a result of
bad luck is unacceptable in any environment where you have to
be careful about limited memory.

Well of course it is MUCH easier to introduce this kind of
specialized GC, you should be able to do the same in Ada by
simply defining an appropriate storage pool.
