I poked at this a bit more and it is looping in
int_process::waitAndHandleEvents(bool block)

I ran the previously posted test on ppcle XX

./mutatee.10 100 & DYNINST_DEBUG_STACKWALK=1 DYNINST_DEBUG_THREAD=1
LD_LIBRARY_PATH=/root/dyninst-10.0.0/install/lib
DYNINSTAPI_RT_LIB=/root/dyninst-10.0.0/install/lib/libdyninstAPI_RT.so
./mutator.10  $!

captured the output of that, then to trim it down a bit ran it through:
  awk '/mailbox size/ {print "##### " $0} /Event.*added/ {print $0}
/Handling event/ {print $0}'

which results in (repetition at #####)
