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...
