Unless you link with libjemalloc_pic.a statically, you'll have a new
dependency (on jemalloc.so). I've heard some users don't like new
dependencies in minor upgrades.
No other issues that I know of.

Nothing major that I'm aware of.

MariaDB doesn't bundle jemalloc (not even in 5.5, as far as I know).
