If you check on the Kernel Patch, on signal.c (sys_new_s_context function)
you will see something like:

#define MAX_S_CONTEXT 65535

if (alloc_ctx == 1) { ... }
else if (alloc_ctx > MAX_S_CONTEXT) {
 alloc_ctx = 2;
}

I assume that when the countern reach 65535, they restart the count at 2
(Context 0 and 1 are reserved).
