Thanks both to Jonathan and Perrin,

w/o mod_perl loaded the httpd process does not grow a bit even for 3000+

Devel::LeakTrace shows a leak right after the return from my handler routine.
If I remove the `$r = shift` [and further $r usage], I does not show anything
in the log. I guess it goes deeper inside the Apache::* stuff.
The procedure I am following is:
1. use Devel::LeakTrace # inside the My::Dummy module
2. make 2000 requests to the url
3. killall -HUP httpd (httpd started in single mode)
4. see the httpd error log

yes, only this module. No DBI, nothing.

You're right, I was trying to get rid of any module use from within my module,
even the Constants package.

(top output: SIZE/RES)
6276K 4652K # at startup
6312K 4676K # after first request
7624K 5992K # after 1000 requests
8984K 7356K # after 2000 requests
I've removed event the `$r = shift; $r->* stuff`.
The package now looks like:
====
package My::Dummy;
use strict;
use warnings;
sub handler {
print <<EF;
Content-type: text/html
boo?!
EF
return 0;
}
1;
====
.. and the httpd.conf:
====
PerlModule My::Dummy
<Location /mem>
SetHandler perl-script
PerlHandler My::Dummy
PerlSendHeader On
</Location>
