This is fixed in -49. Note, however, that not all information in /proc/stat is available on 64 bit machines. Some of the information printed in /proc/stat, namely the swap_in/swap_out pages, require access to the SystemPerformanceInformation category in a call to NtQuerySystemInformation. The structure returned by this call is also different on 64 bit systems, even when running under WOW64. The SYSTEM_PERFORMANCE_INFORMATION structure was already undocumented on 32 bit systems, and on 64 bit systems it's even more undocumented, if that's possible :) Unfortunately, to date there's no official replacement function which provides the page read/write count. So, on 64 bit systems, this information is set to 0 in /proc/stat.
