This is good news. I changed ADDRESS_IN_RANGE to a function, 
then suppressed it. There were no other uninitialized memory reads.
Valgrind does report a bunch of problems with pthreads, but
these are likely valgrind's fault. There are some complaints
about memory leaks, but these seem to appear only to occur
when spawning/threading. The leaks are small and short lived.
