swap_pager_getswapspace

[Erich Dollansky]

Hi,

there was recently a long discussion regarding this. My solution is to
create a file-backed memory disk and use it for swap when the media is
not able or has to be reformatted. I still use the old-fashioned 2 *
RAM size to determine my swap space. It seems overkill but I never had
problems with this saving a lot of my time.
