The function schedule() is never directly activated by the timer interrupt handler. Instead, when the timer irq handler notices the scheduler should run, it sets a flag. After the irq handler has finished (and quit), the part of the kernel that is responsible for switching back to userspace mode notices that the flag got set. That part of the kernel, running in process context, then calls the scheduler. -- "Debugging is twice as hard as writing the code in the first place.
