Modern threading implementations are pretty good. Plus, a lot of the memory threads use is just virtual address space, not real memory. On 32-bit systems you ran into the problem of running out of virtual address space with a few hundred threads. With the popularity of 64-bit platforms this problem has gone away. Plus, because this is C, it's trivial to reduce the stack size to, say, 512 KB without too many problems.
