And you have to look everywhere for other changes to signals, which 
could override yours.

Frankly, I wonder whether its worth spending time on gprof, which is 
pretty much useless in my experience with ffmpeg. Why not try instead to 
move to say, oprofile? I admit having no experience with it, but I read at

http://www.cs.utk.edu/~vose/c-stuff/oprofile.html

"Note that unlike gprof, no instrumentation (-pg and -a options to gcc) 
is necessary.

Periodically (or on opcontrol --shutdown or opcontrol --dump) the 
profile data is written out into the /var/lib/oprofile/samples 
directory. These profile files cover shared libraries, applications, the 
kernel (vmlinux), and kernel modules. You can get summaries of this data 
in a number of ways at any time."

which sounds great.
