This is perfectly normal behaviour:
1) on your system, you have no process limit configured for yourself so you can start processes until all resources (memory, file descriptors, ...) are used
2) when all processes are used, there really is no way the kernel can buy you more hardware on ebay and install it on the fly ... all it can do is start failing allocations
On production systems, good admins setup per-user limits for the various resources so no single user is able to run the system into the ground.
