* Windows doesn't overcommit, so we can't do this on Windows
From [http://msdn.microsoft.com/en- us/library/windows/desktop/aa366887%28v=vs.85%29.aspx the documentation for VirtualAlloc] it seems like it's possible to first reserve a memory range with `MEM_RESERVE` and then commit it as needed with `MEM_COMMIT`. [http://blogs.technet.com/b/markrussinovich/archive/2008/11/17/3155406.aspx This article] confirms it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9706#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
