This happens on Windows 7 64 bit while on Windows XP everything is fine.
The interesting thing is that 3727360 / 1024 = 3640, so it seems that 
either WMI or our code is wrong.

WMI docs for Win32_Process class 
http://msdn.microsoft.com/en-us/library/aa394372(VS.85).aspx -----
*PageFileUsage*
Data type: uint32
Access type: Read-only
Qualifiers: Units (Kilobytes)

Amount of page file space that a process is using currently. This 
value is consistent with the VMSize value in TaskMgr.exe.

Example: 102435
-----

So it looks like WMI is reporting kilobytes, not bytes. We'll need to 
either convert our bytes to kilobytes, or convert the WMI results 
into bytes for comparison.

Problem seems to be that apparently WMI on Windows XP reports bytes 
while on Windows 7 reports kilo bytes.

Since I have no clue on why this happens I used a workaround in the 
test suite ( r637 ) which now assumes Kb on Windows 7 and bytes on all other systems.

Status: Fixed

Updated csets after the SVN -> Mercurial migration: r637 == revision 15c646a51f73
