Ok, back to `tm_basic`

Then it seems for me this will be more clear

#ifndef max
#define max(X,Y) ((X) > (Y) ? (X) : (Y))
#endif

#define N_THREADS_MAX  ((CYGMEM_REGION_ram_SIZE/16)/CYG_THREAD_OVERHEAD)
#define NTEST_THREADS  max(2, N_THREADS_MAX)

and it's all. I dislike to add that `NTEST_2_THR` (may be N_THREADS_MIN)
and I've seen no sense to tweak those for loops. What do you think?
