Why have a cyg_thread_delay function if you can just set up a one shot alarm
each time you want to delay? Because it's more convenient and keeps
application code cleaner. It's hard to argue that something is absolutely
necessary, because in reality ecos itself is not absolutely necessary.
People use an RTOS because they don't want to have to code all the things an
RTOS does themselves. I don't want to have to set up alarms and DSR's every
time I create a new periodic thread.

What if it was configurable as something like
CYGFUN_KERNEL_THREADS_PERIODIC?
