Fix pthread_join check for valid thread handles
On Linux, checking for > 0 worked because pthread_t is internally an
integer type. On other platforms (*caugh* Mac OS X *caugh*), it is
typedefed to an opaque pointer, causing a warning if used in an
integer relational comparison.
The intended use is to allow the generic cleanup function to be used
in the error path of the block processor creation function, while
preventing pthread_join being called on threads that haven't been
created at all. Since they are calloc'ed to 0, testing for non-zero
values should suffice in both cases.
