I wonder why you say Linux is less flexible? Couldn't you just write a custom allocator directly using sbrk()? Also, 32 bit linux process leaves more application space free, so you can easily reach 2Gb process size, while I recall windows XP having issues after 1.5Gb. It's been a while, so I might not recall all details...
