A google search for "erlang million processes" turns up many links, one of
which being:

  http://en.wikipedia.org/wiki/Erlang_programming_language

"It should also be noted that Erlang processes are neither OS processes nor OS
 threads, they are lightweight threads somewhat similar to Java's
 'green threads'. As a result, Erlang processes are extremely lightweight (the
 estimated minimal overhead of an Erlang process is 300 bytes) and a very large
 number of them can be created without performance degradation (a benchmark
 with 20 million processes was tried[1])."

And the link for the benchmarking:
