If you're looking for a *guarantee*, then you cannot even use malloc(). 
Malloc has unbounded time, and is not predictable.

The approach most real time programmers use to deal with this is to 
preallocate all needed data before entering the real time section, and 
the real time section does no malloc's or free's.

Also, you can use malloc and free in D, in exactly the same way you 
would in C.
