tests: limit number of threads to something reasonable.

Browse Source 
Creating 1000 threads with the default stack size of 8 MiB will fail on
architectures with a 32-bit address space. Move up the existing THREADS
macro and use that instead, but change its definition to 1000 if
pointers are larger than 32 bits.
