...from balancing irqs across different physical cpus, or will that override the setting if there are too many interrupts and one of the cpus is overloaded. Example: i have 4 cpus and i have configured irqbalance= off, so there is no irqbalancing done by xen. Now if i have affintized all my physical interrutps to one cpu say cpu1 all the interrutps shpuld be handled by the cpu1 and so should all the softirqs generated. Now what happens if one of the other cpus is lightly loaded, will some of the softirqs be queued against the other cpus or will cpu1 handle all interrupts and softirqs. Looks to me like t...

With tryCatch() it is possible to catch interrupts with tryCatch(). Then you can use a 'finally' statement to clean up, release resources etc. However, how can I "protect" against additional interrupts? This is a concern when the hold down Ctrl+C and generates a sequence of interrupts. Example: tryCatch({ cat("Press Ctrl+C...\n"); Sys.sleep(5); }, interrupt =
