The memory_limit should also be taken into account when uploading files to PHP. We need to extend the file upload sanity checks to include a check for memory limits that might be too low.

guess that needs some testing, testing and testing to find sane numbers. no idea what base mark to take into account for the code and how much to calculate for each mb uploaded.
