You're right it will consume more memory, but most of this memory is shared (well, in *nix land it is, even in some OSes have problems reporting shared memory).

You can reduce the number of apache children (and db connections) you need per application by running a simple lightweight proxy in front.

    Yes, I know... httpd scaling has some limitations, especially, when non-shared part of httpd-children takes ~15M (which is not good state, I know).
    Imagine, that two similar legacy applications run under Apache, using the same db and sharing some perl modules. But, acidentally, one of them uses old version of MyFamily::Session and the second uses newer version of this package...

[LanX]: probably I need to teach the app to restart after C-c Kill
[Corion]: LanX: Maybe have an infinite-loop cmd file? Much easier than trying to manage that from within Perl IMO
[Corion]: Alternatively, relaunch the application from cron (or a Windows cron) every minute
[LanX]: will try infinite loop ...
[Corion]: :START ... goto START
[LanX]: oh .bat you mean?
[LanX]: obscure cult ...
[Corion]: LanX: cmd.exe is just another way to launch Perl
[LanX]: I know its a cult... and I repent it every time
