In general the idea of waiting 2 whole ticks with interrupts disabled is such a bad idea that I don't think you will find a pre-existing API to do that. You definitely will not be able to simply check a variable because with interrupts disabled, their is no one to update the variable. If you really need this, you will likely need a call into a routine the gets the current time from a hardware clock. IMHO, such misbehaving code will never get into mainline and is not even a good learning experience.
