It would be nice for modest system to be able to use small ramdisk without limiting the total amount of swap disk.
at the moment, if I create a 4GB ramdisk, even if I provide a path to a SSD, the total amount of swap will be limited to 8GB which is obviously too low. It's unfortunate, for instance on laptop, because a 2-4GB ramdisk could really speedup PI if PI could use that ramdisk for the most recent histories or caches and use the SSD when the ramdisk is out of space (or to move out older stuff from the ramdisk)
