If I'm not mistaken the memory is allocated, but it is virtual memory,
so unless it is actually used there is no penalty.

The only problem with allocating too much stack space is that you can
run out of address space on a 32 bit JVM.

With typically 2GB max addressable for the app and 10 MBytes per stack
you are limited to 200 threads.
