[debian-mysql] Bug#832931: (no subject)

[Daniel Black]

As Thadeu Lima de Souza Cascardo said, the build time detected page size
isn't correct, perhaps using --with-lg-page=/--with-lg-page-sizes at
compile time.

This is available in the 3.6.0 version of jemalloc. (upstream currently
at 4.4.0). I've got part way though an upstream patch to change this to
runtime detection, no idea when it will be complete, and I have been
told that upstream won't risk performance regressions.
