Talk:Ruby Hacking Guide/Threads

"Strictly speaking, on multi-CPU machines one can run two threads at once, but even so, if there are more threads than CPU’s, then the threads must run in turns"

Honestly that is complete bullshit. Most of the modern CPUs implement threads on hardware. I work daily with a system that can run some 1560 threads simultaneously. Given the software uses real threads offered by the operating system (which uses the CPU architecture correctly) instead of some silly green threads and kin.
