I don't know anything about the perl interface, and unfortunately I don't
think you'll find very many in here that do. (I hope I'm wrong.)

There's no such list provided by libcurl itself at least. And the "number of
running processes" is not increased by libcurl since 'multi' does not imply
threads, just multiple transfers. It does all transfers in the same thread.

But each call to curl_multi_perform() does inform the caller about how many
transfers that are still "alive" (ie not done yet).

curl actually does not provide any 'multi.pl' example, you must be referring
to the WWW-Curl package (from CPAN). But no, I don't know how that is
used/done. In libcurl you read out the post-transfer information such as that
with curl_multi_info_read(), but you seem to have figured that out already.
