Might be a good opportunity to look at #120

This looks like a same issue as for DBD::MariaDB from comment: perl5-dbi/DBD-MariaDB#80 (comment)
(Temporary) fix for DBD::MariaDB: perl5-dbi/DBD-MariaDB@7752126
It seems that OpenBSD malloc overhead is bigger then on Linux. Some more debugging is needed.

Note that p5-Proc-ProcessTable-0.53p1 results in

t/60leaks.t ............................. skipped: module Proc::ProcessTable does not support size attribute on current platform

So this needs a newer version of Proc::ProcessTable (the test report says 0.55)

OpenBSD has MALLOC_OPTIONS, but using that to enable/disable features doesn't seem to make a real difference.

This seems to happen with both clang and gcc (as expected)

"malloc(3) randomization implemented by Thierry Deval. Guard pages and randomized (delayed) free added by Ted Unangst. Reimplemented by Otto Moerbeek for OpenBSD 4.4. "

The plan here is to re-write the test.
