For fixed regions (cygwin/user/myself/shared console), try fixed address first. Fallback to non-fixed region. Don't even try fixed address if the Cygwin DLL gets dynamically loaded. For non-fixed regions, try to allocate in a loop within the area from SHARED_REGIONS_ADDRESS_LOW to SHARED_REGIONS_ADDRESS_HIGH.
