--- Comment #11 from Julian Maurice <julian.maurice at biblibre.com> ---
I can confirm that with this patch, if I restart mysql server, koha is no
longer able to connect to mysql until I restart (or reload) starman.

Looking at the test script and times, this seems to save ~40μs by call (~8s /
200000 calls). That's not much. Do we know how many times by page dbh get
called ?

Changing status to Failed QA. The patch introduces a regression and I think we
need more precise profiling data before changing the implementation of dbh.
