Glad to hear it's working better for you now.

Swap use is dynamic, exactly as you describe.  What isn't dynamic is the
on-disk structure in which the kernel stores the swapped pages.  AFAIK, that
must be statically defined in terms of size either for swap partitions or
swap files.  Disk space is so cheap, and swap space is such a small fraction
of modern disks, that the coding effort is not anywhere near any payoff
achieved with truly dynamic sized swap structures.
