ml2json mail archive processor

Recent perl needed to avoid leaking

The use of functional programming idioms as described in hacking works fine on perl v5.14.2, but some older versions of perl like v5.10.1 have a bug or bugs that lead to leaking of memory. ml2json still works on rather big archives, but may require a few 100 MB of RAM or so (depending on archive size). This is also the reason that ml2json is a wrapper script around ml2json_ that increases the stack size, so that when such a perl finally releases the leaked structure, it won't run out of stack space.

If the leak precludes you from using ml2json, and updating to a newer Perl that doesn't leak is not a solution for you, I might be able to find a workaround. Contact me and I'll tell you what I can do.
