Under which condition does a full garbage collection take place? Does
the interpreter run a full gc once in a while or is it started by
gc.collect()?

I'm more concerned about the int and float memory blocks. They should
get freed when more than a couple of hundred blocks are allocated. The
other free lists are much smaller. But memory fragmentation is an issue
for them, too.
