In an out-of-date sid chroot, with latest openjdk-7, on kfreebsd-9 kernel;
I can run the sw_macros_test 100 times without reproducing it.

Then I built in a clean, up-to-date sid chroot on another machine, with
kfreebsd-10 kernel, and reproduced it the first time, during package
build.  This is good, from here I can start to eliminate the variables
and try again.

I attached gdb to the hung cppunittest process (which seemed idle, not
in a busy loop), and something is waiting to acquire a mutex;  probably
a lock held by another thread:

I'm sure there are other threads running, but gdb doesn't see them,
that's a limitation of gdb on kfreebsd at the moment.  Attached the full
backtrace anyway for now.
