Best and fast way to AllocMem within an interrupt :Semaphores ?

Slightly off-topic

Does anybody have any performance statistics for the different memory allocation functions supported by exec?

I'm interested in the time taken to allocate/deallocate as a function of allocation size, for each method*


*I'm fully aware that this would likely change as memory becomes fragmented.

Presumably then, they all have at least O(N) cost as a function of the number of nodes in the free memory list?

I'm interested in all of this as I weigh up the cost of writing my own custom allocator routines versus a basic wrapper for the memory pool allocation scheme.
