Hmm, well I could argue that using the macro for all allocators, apart from alloc_commit_node(), clearly shows which allocator is the odd-man out (and conversely, that all others are the same)! :-P

No, I don't think this is a telling advantage; I don't think it makes that much difference. (six of one, half-a-dozen of the other).

BTW, I tested the previous series on Linux 32-bit, Cygwin 32-bit, MinGW 32-bit and Cygwin 64-bit. (I can't test on Linux 64-bit, since I can't get Linux installed on my new laptop :( ). Admittedly, the testing on MinGW and Cygwin was only fairly light (it takes *hours* to run the full testsuite, and I just don't have the time).

I was slightly concerned, when reading through this new series, that the alloc_node() function may no longer be inlined in the new allocators. However, I have just tested on Linux (only using gcc this time), and it was just fine. I will test the new series on the above systems later (probably tomorrow) but don't expect to find any problems.

Yep, this looks good. Thanks!
