The directory management happens in the C code, long before any Perl gets
involved.

You have to use the filesystem for that.

We don't need that.  You can just use Storable to dump/restore data
to/from a file in the current directory.  I don't think that needs
a wrapper; it's already very simple.

All Mailmunge callbacks are invoked with the temp directory being
the current working directory, so you can use relative pathnames
to create files in the temp directory.  If you need the name of the
temp directory, it's $ctx->cwd.
