I don't do that.  I just give classes destructors, return error from the
function and let the compiler clean up.  (I never call pthread_exit; I always
exit a thread by returning out of it, since objects need to go out of scope
to be destructed, and I avoid C++ exceptions due to code bloat.)  I try
to avoid all cases of sprinkled-cleanup-code (not that I'm always successful).

(I don't know if that's relevant here--very little experience with coroutines--
but it's worth mentioning.)
