<p>Andrew,</p>
<p>I don't see myself much value to the mutexes with timeout, at
least in how they are used within GDAL. What you underline was
actually reported in <a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/issues/3631">https://github.com/OSGeo/gdal/issues/3631</a>.
The fix would be to use a non-timeout mutex</p>
<p>Even<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I'm looking at code in gdalwarpkernel.cpp and there are
calls to CPLAcquireMutex that take a "timeout" argument. From
looking at cpl_multiproc, on a non-windows system it seems the
timeout is ignored, but on WIN32 it is respected in the call,
but the return value is generally ignored, meaning that the
subsequent code could run without the lock having been
acquired.</div>
<div><br>
</div>
<div>This seems like strange behavior. Is there a reason for the
different behavior on Windows and not-Windows? Am I missing
something?</div>

</div>
<div>Thanks,<br>
