Yes, the API contract isn't "don't interrupt me during this critical section" it's "if you have to interrupt me during this critical section, go to this recovery/restart code". There is a time-slice extension feature in the works that's roughly "please let me finish this critical section before you interrupt me". But a hard guarantee that userspace code won't be interrupted is probably untenable in a preemptive multitasking system. | ||
