Builds and tests fine both on Debian Lenny w/ Apache 2.2.9
and perl 5.10 and Ubuntu 10.04.

I seem to understand that our current SizeLimit config (below) will
be completely bogus with the new version, right?

<Perl>
   use Apache2::SizeLimit;

   # Will prevent murders of immature children that just needs to grow a bit
   $Apache2::SizeLimit::CHECK_EVERY_N_REQUESTS = 30;

   $Apache2::SizeLimit::MAX_PROCESS_SIZE = 470_000;
   $Apache2::SizeLimit::MIN_SHARE_SIZE = 50_000;

   open(DATA,"</proc/meminfo");
   my ($mem) = <DATA> =~ m/MemTotal:\s+(\d+)/;
   close(DATA);

   # See Practical mod_perl page 352
   #  
int(($mem-1000000-$Apache2::SizeLimit::MIN_SHARE_SIZE)/($Apache2::SizeLimit::MAX_PROCESS_SIZE-$Apache2::SizeLimit::MIN_SHARE_SIZE));
   # We can't use the super-cool practical mod perl recipe, because
   # of how Apache2::SizeLimit (or Linux::Smaps) reports process memory on  
Lenny
   # It used to be 110Mb, now it's 440Mb. (???)

   # And reserve 500Mb for the OS in any case
   $MaxClients = int (($mem - 500) / 100_000);

   warn "\nMemory: " . int($mem/1000) . "Mb, MaxClients: $MaxClients\n";
</Perl>
