If you configure --enable-zsh-heap-debug you can edit mem.c to set a
value for the heap_debug_verbosity variable which will cause a LOT of
debugging messages to be printed to stderr.  This may tell you where
it's spending time.

Shell variables are always passed around internally by value rather
than by reference, so operations on a big list will copy it a lot.
