[GD-Windows] Win2K SP2 debugging slowdown?

[Javier A. <ja...@py...>]

Hi all,

We have been tracking a weird situation we have, where on some of our dev.
machines our game takes several seconds to shut down. We eventually found
out the following:

- The game must be running in a debugging session under MSVC (haven't tried
other debuggers).
- The computer must have Windows 2000 _with_ service pack 2 installed.

The slowdown happens during a loop that deletes several thousand dynamic
memory blocks. Most of the time, sometimes it doesn't. Similar symptoms also
appear in other places, like our streaming music decoding thread.

Running MSDEV under VTune we found that, when the slowdown happens, most of
the time during that loop is spent inside the operating system, spread
half-and-half in two functions: RtlCompareMemoryUlong() and
RtlFillMemoryUlong().

Has anyone heard of something like this?
