[osg-users] DatabasePager::DatabaseThread is crashing when DatabasePager has been deleted

[Robert Osfield]

HI Hartwig,

Could you explain what you think the bug is as copying pasting some
bit of code without any explanation is a bit too obscure to divine
what you mean.  I presume it's you who's added the #if 0 #endif around
the startThread() calls as this code is not the same as master/OSG-3.6

Robert.
