I dropped the limit to 128MB and now the simple test program fails at 1900MB. 

Setting the LARGE_ADDRESS_AWARE flag does not seem to make any difference
though:

$ i686-pc-mingw32-gcc -o test.exe test.c -Wl,--large-address-aware
$ i686-pc-mingw32-objdump -p test.exe  | grep large
        large address aware                                                     
$ wine ./test.exe
...
Allocated 100MB of data in 1.93 seconds (51.79MB/s)
malloc(4096) failed at 1900Mb

This is with wine-1.1.6 + your patch, adjusted to 128MB. It is a 64 bit host w/
4GB of RAM + 6GB swap.

Any ideas?
