Hi David,

sounds excellent, we'll definitely be trying it out.

Should we expect the Darwin version to be close to stable as well or should we concentrate on Linux only?

Cheers, Gerwin

Hi Gerwin, The reason I've concentrated on Linux is simply that I don't have a Mac. I can use the Macs at T?M but provoking them to start paging isn't friendly to other users. It's likely that the current code will work equally well on Mac OS so go ahead and try it.

Windows/Cygwin is a somewhat different matter. There's no easy way to detect paging on Windows. The page fault counter that is available actually returns the soft page count and apparently this is what Cygwin returns as the hard page count. I've had to use an undocumented interface to get the paging count in that case and it may overestimate it. I'll just have to see how that works.

Regards, David
