I've realised, that quite often, much of my hardest coding work is where I have to rewrite memory allocation routines, or make a new one. For example, I had to write my own wrapper around NewHandle/SetHandle, so that it does sentinel checking, and reallocation in ways that I prefer (attempts to alloc in temporary memory first, then application memory if that fails) and a few other things.

Another allocator I'm considering writing is designed to allocate blocks contiguously, the blocks have two sizes possible. The idea of this allocator is for a high performanc library, I want to keep the data all in the same cache, my allocator is designed to do that both with locality, and low overhead.

Now, it's really getting a bit tough coding, and its on such a simple task. I'm thinking that gnarly code like this, is why malloc was written, even though malloc isn't good enough for this need.

So, I'm wondering if there are such things as alternate allocation libraries available? Not ones that replace malloc, but ones that offer an alternative (and also leverage malloc also).

Any ideas anyone?

At least give me some productive key words to search for that will give good results on google :)

Thanks a lot!
