I'm using cooperative threads in NOX to handle asynchronous SNMP

in my code. Does the programmer dictate the scheduling of threads in
the cooperative thread model?
Right. In co-operative threading model the programmer explicitly (by
calling yield) or implicitly (by blocking) instructs the scheduler to
run the next thread in the same thread group.
An easier/clearer question to answer would be the following:
Suppose thread t1 starts a new cooperative thread t2. Does t1 get
rescheduled by the processor only when t2 yields/blocks/exits?
Exactly right again. Note though, the t2 won't run before t1 yields/
blocks/exits for the first time after it has created the thread t1.
