Actually for completeness there is a place where it allocates local memory for max I/Os * 4, and that 4 is a not entirely unbogus and should change to io_combine_limit for the AIO stuff. Patches in progress, more soon. But that'd not be using MAX_IO_COMBINE_LIMIT or the number of system-wide I/O, it'd be your (usually much smaller) configured limits. But I'll write about that with more details in a new thread...
