I have several possible solutions to this and am thinking about implementing one
of them:
1) Completely scrap the routines in malloc.c and replace them with a thin
wrapper around the core Windows memory allocation routines.
2) Attempt to implement a windows version of mmap() and enable that feature for
large allocations.
3) Attempt to clean up the malloc routines so they are less picky about the
address ordering of chunks allocated from the system.

Option 1 is currently available with the compile time option
LEA_MALLOC = NO in src/gnuwin32/MkRules.  I doubt if we would
incorporate patches to do 2 or 3, because this sort of stuff is so
hard to test and debug, but you're welcome to do it for your own use.
If you do, I'd recommend talking to Doug Lea, the author of our
current malloc, about incorporating your ideas into his code.
