yes, ksoftirqd should just avoid you to eat all the cpu even if you keep
posting the softirq all the time. ksoftirqd is reniced at +20 so it
should be pretty nice with the other tasks in the system.
If you want to delay the softirq and run it at a low frequency then you
should use a timer or another functionality (the softirq is required to
run ASAP always).
I hope I didn't misunderstood the question in such case please correct
me.

PS. I will be offline shortly so I may not be able to answer further
