void* PL_malloc_atomic(size_t
bytes)
void* PL_malloc_uncollectable(size_t
bytes)
void* PL_malloc_atomic_uncollectable(size_t
bytes)If Boehm-GC is not used, these are all the same as PL_malloc().
With Boehm-GC, these map to the corresponding Boehm-GC functions.
Atomic means that the content should not be scanned for
pointers, and uncollectable means that the object should never
be garbage collected.
