I'm no Linux expert, so I have no clue here.  Perhaps the C libraries already
have some method?

There is none that I can think of.  In fact, the Windows drivers allow both the
debug and release versions of the user-mode components to co-exist, as well as
mixing debug and release kernel drivers.  This makes it easy to debug a single
component without affecting timings in the whole stack.
