That's exactly the case with this set of patches. There's a set of
TRACE_POINT macros that are required for users to toggle areas where
they want to see the backtraces and also an DISABLE_BACKTRACES macro to
turn this feature on/off globally.

It also respects the NDEBUG macros, so as not to impact performance when
debugging is disabled.

I'm still working on cleaning up this patchset, but if you'd like to see
the documentation directly from the passenger sources, you can find it here:

https://github.com/FooBarWidget/passenger/blob/master/ext/oxt/backtrace.hpp

The forked boost is here:
