Description (last modified by warmerdam)

Hi, While debugging my application I get a kernel resource leak. The following is the call stack. The application is only calling GDALAllRegister() and GDALDestoryDriverManager(). The same leak happens with the example applications. I've also tried older versions of gdal. My OS is windows 7 and I tried both x86 and 64bit.

I have cleaned up this and a few other mutexes on cleanup (r22812); however, there are still a few that are hard to cleanup properly. Generally speaking I don't take one-time allocations like mutexes too seriously, but it is nice to clean them up to make finding other (serious) leaks easier.
