Yes. There are no limits in eCos on the number of threads you can
create. The scheduling algorithms are all constant-time, so scheduling
latency is independent of the number of threads in the system.
Obviously the latency between a thread being woken up and it actually
starting depends on how many other threads of higher priority are
current running, but that's true of any OS.
