That's an endless loop. How does one measure, if it's leaking memory?

These 2 snippets aren't related at all. The latter is dealing with freeing
sys-malloced memory as the comment is saying. The former is plain string
memory allocation code.
I'd presume, that the string memory compaction code i.e. 'compact_pool()' is
never run in the loop above.
