[Paraview] Is There An Error In vtkSocketCommunicator (2.4.2)?

[Amy Squillacote]

Earlier this afternoon I committed a fix for this problem to the CVS 
branch for ParaView 2.4.  It will be in the next patch release of 
ParaView 2.4.  If you want to get the fix for this now, check out 
ParaView with the tag ParaView-2-4.
