Comment (by leavengood):

 I have several of these VM bugs in my ticket list, I should have worked on
 them before we started working on the alpha4 release. Because it seems
 like they might need to be fixed. With the amount of RAM some people can
 have (such as myself) it is insane to have 16 GB of swap when you have 8
 GB of RAM. For one thing it will probably never be used on Haiku, and in
 general that is way too much swap.

 I think the sizing heuristic needs to be just a tad bit smarter ;)

 It should have a reasonable maximum, like 2 GB, and it should take into
 account both the total size of the disk and the available space on that
 disk. When it has calculated a reasonable size, it should check for the
 settings file and create it if it doesn't exist and put in the chosen
 size.

 And the initialization code should check the VM settings and delete the
 swap file if the settings exist and a current swap file exists, but the
 virtual memory is turned off. That should be inside the if statement on
 line 1345.

 I think if all the above is done most of these bugs will be taken care of.
