[Insight-developers] itkWarningMacro not thread safe?

[Williams, Norman K]

I was trying to chase down an intermittent bug in one of our programs,
BRAINSTransformConvert.

Without going into my particular issue too much, the problem is that
BSplineDeformableTransform::TransformPoint prints out an warning message
using itkWarningMacro, and the underlying print mechanism --
itk::OutputWindow -- is apparently not thread safe.

I logged a Jira ticket about it and will submit a patch
https://itk.icts.uiowa.edu/jira/secure/EditIssue!default.jspa?id=18327

My question is this: Is it reasonable to expect that itkWarningMacro (and
behind the scenes itk::OutputWindow) be callable from a multithreaded
filter?  If so, could itk::OutputWindow be made thread-safe?
