<br>
Due to bug # 4846 discussed here:<br>
<br>
<a href="http://www.itk.org/pipermail/insight-users/2007-April/021842.html" target="_blank">http://www.itk.org/pipermail/insight-users/2007-April/021842.html</a><br>
<br>
the Mersenne Twister is not thread safe. A side effect is that the<br>
random iterators are not thread safe.<br>
<br>
Luis's suggestion to convert the MT back to a normal Object seems the<br>
most sensible, however since this hasn't happened, maybe it would be<br>
easier to add mutex locks around the few Get*Variate*() calls<br>
affected? Or can we at least add it to the documentation that these<br>
are not thread safe?<br>
<br>
What do people think?<br>
<br>
<br>
Thanks,<br>
Neil<br>
