read() is not behaving as a cancellation point, only setting the cancel
type to asynchronous permits this testcase to terminate. We do have the
pthread_setcanceltype glibc/libpthread hook in the forward structure, but we are
not using it: the LIBC_CANCEL_ASYNC macros are void, and we're not using them in
the mig msg call either.
