rtems_iterate_over_all_threads

Not meaning to be a pain but, you could solve this by making the urgent task
non-preemptive or making it the highest priority thread. In either of these
ways, no other threads will be able to run unless the urgent task
relinquishes the CPU.

 

By the way, another small note: suspending all other threads can be very
time consuming... (if you have too many threads)
