This much is a good thing - exactly what the commit was intended to solve.

But it doesn't gel with:

(In reply to comment #5)
> #5  0x000000000053dcee in stap_waitpid (verbose=<value optimized out>, 
>     pid=15428) at ../systemtap/util.cxx:618

This line is the clog which prints the "Spawn waitpid..." above, plus

> #8  systemtap_session::remove_tmp_dir (this=0x7fffe37b6830)
>    at ../systemtap/session.cxx:1781

This is a couple lines before that which prints "Removed temporary directory".

So I don't see how that backtrace could possibly correspond with the new
output.
