Well, it is not really a DoS. The rescheduling of the process is limited by the scheduler and the available CPU time (depending on the number of runnable tasks in the system).
Shouldn't an unprivileged process be rate limited somehow to avoid flooding the machine with interrupts? We restrict nonroot users from setting the RTC interrupt rate higher than 64Hz for a similar reason (granted, this limit dates back to the 486 days and should probably be increased to 1024 Hz). Root and SCHED_FIFO tasks could be exempt from rate limiting, to avoid the need to introduce a new rlimit which would take years for userspace to catch up to.
