Previously, some WMI based checks, such as msexchange and dotnet_clrmemory, would crash and generate a crash report if a WMI timeout occurred. Since WMI timeouts are expected to happen occasionally, this behavior was not appropriate. Moreover, these crash reports provided no useful diagnostic information and only cluttered the disk.

Now, instead of crashing, all WMI based checks will correctly handle the timeout by skipping the data,
eventually setting the service state to STALE,
thus making WMI monitoring uniform and consistent.
