cmogstored 1.3.2 - FreeBSD shutdown speedup

This release speeds up graceful shutdown on busy systems such
as FreeBSD.  There is also a minor resource savings for users
of the undocumented --worker-processes switch.  There are also
some minor memory error fixes for test cases (which did not
affect the daemon itself).

Upgrading is optional unless you are affected by these fixes.

Note: GNU/Linux users are encouraged to read the manpage update
regarding glibc malloc arenas
