So I would ask, as your memory climbed, did the system slowdown, or did things keep running normally.

I watched the RES column from ps's output, first via top, then also using a code snippet taken out from Process::MaxSize like
[...] my $size; open PIPE, "/bin/ps wwaxo 'pid,rss' |"; while(<PIPE>) { next unless /^\s*$$\s/; s/^\s+//g; chomp; $size = (split(' ', $_))[1]; } close PIPE; return $size; }
I didn't wait to let the system really slowdown, but stopped when it became obvious that swapping would have to start.

[haukex]: $? and system - the exit code of a process is stored in the upper bits of $?, so >> 8 does a bit shift to get at it
[hippo]: (truncating)
[erix]: aah, yes haukex++
[hippo]: Re: DBD::Sqlite queries slow - and gives wrong results has 6 upvotes. Is everyone quite well?
[erix]: hippo I think the 26 downvotes sick
[erix]: eh, 29 downvotes
[erix]: but I guess there's no stopping the herd
[1nickt]: Thank you haukex and hippo. I'm thinking of using IPC::System:: Simple::capture instead. But will go reread Hauke's treatise first :-)
