Again, it's an option I had considered, but there are two problems
there. Firstly, "One problem with gprof under certain kernels (such as
Linux) is that it doesn't behave correctly with multithreaded
applications. It actually only profiles the main thread, which is quite
useless." (http://sam.zoy.org/writings/programming/gprof.html)

There appears to be at least one workaround for that, but the other
problem is that it involves recompiling the program and its shared
libraries (our libraries, that is, not system ones) with profiling
support. I'm trying to work towards a transparent, drop-in solution
that will work on existing executable images that are as close to what
we'd actually release as possible, hence looking for an
LD_PRELOAD-based solution.

Dan.
