Valgrind's internal model of threads is [was] not isomorphic to
the model used by the Linux kernel+glibc.  There are control,
scheduling, and "multiplexing" issues.  Also, there is the problem
that Linux has [had] two models: (old) linuxthreads and (new) nptl.
A different product, such as Insure++, may work sooner.
