Perl can, yeah. If a
perl -V
shows a "usemymalloc=y" in the output somewhere then perl's using its
own internal malloc and you're definitely never going to release
memory to anything. If it's 'n' then it'll use the default malloc
scheme -- I'm pretty sure for embedding use it uses whatever routines
the embedder defines, but it's been a while since I've poked around
in there.
Anyway, if perl's using its own memory allocator you'll want to
rebuild it to not do that.
