[mapguide-users] MGOS2.0.1 & Raster Files Performanc

[Zac Spitzer]

I think the problem with the crashing isn't caught by the FDO unit
tests because the problem happens after a while and the unit tests
might not be running longer enough

if anyone want's to reproduce the problem, there is some good sample
the imagery here
which always eventually crashes mapguide
