Does the NVIC really do interrupt nesting?

For days I've been banging my head with a problem that shouldn't take more than a minute time otherwise. How to get the NVIC of Cortex M3 handle the simplest in the world interrupt nesting - an interrupt within interrupt.
In details - I have the SysTick running that executes my handling function. What I am trying to achieve is to re-enable the SysTick interrupt and let the same function be executed should another SysTick has occured while it was still serving the previous one. With the old "dumb" ARM7's VIC that was the easiest thing to do - just enabling the interrupts again once I've entered my function. But with this "advanced" one, a person apparently has to go through some tricks to get the job done.
Any help would be warmly welcome!
Thanks

Thanks for the responses. I can't believe that's true! So bad... The Cortex family has lost me forever. NVIC is a disaster!
