I seem to be getting some lock up when switching threading models in
osgviewer (with the cow). However.... I also see these in 2.6.0 now that
I test it (haven't been using 2.6 yet).
What's more, switching of the threading model with 'm' does not always
seem to happen. Sometimes when I press 'm' the threading model doesn't
change, only when I press 'm' again.
This is with vsync off, b.t.w., in case timings issues might be at play
here.
The lockup always seems to occur when switching to
CullThreadPerCameraDrawThreadPerContext. Here's a relevant stack trace

Hi All,
I am planning to make a 2.7.3 dev release tomorrow morning, there have
been plenty of changes checked in since 2.7.2 so there is potential
for build breaks so I'd appreciate testing across platforms of
svn/trunk.
If you have a clean build or a build failure please post your results
into the list so I can keep tabs on where things are build/what is
left to fix up.
Thanks in advance,
Robert.
