[vtk-developers] potential memory leak/waste in VTK file readers

[Andy Bauer]

I noticed that some of the readers in VTK don't close their files when the
file name changes and a new file is read in.  In some cases this isn't a
problem but in other cases (possibly the netcdf readers) this may be a waste
of memory.  An example of where this can cause problems is the
vtkFileSeriesReader class in ParaView which cycles through a set of files to
read.  I'm emailing this out to everyone to request that if people have a
chance, please check out their favorite reader to make sure this isn't
happening.

Thanks,
Andy
