In Windows, what is the meaning of a crash with exception code equal to STATUS_WAKE_SYSTEM_DEBUGGER 0x80000007?

I have a crashdump created by DrWatson, the exception code is 0x80000007 STATUS_WAKE_SYSTEM_DEBUGGER and the message is "{Kernel Debugger Awakened} The system debugger was awakened by an interrupt." (from here: 2.3.1 NTSTATUS values http://msdn.microsoft.com/en-us/library/cc704588(v=prot.10).aspx )

I cannot find any documentation about it. What is its meaning?

A quick trip to Google brought up this forum post. Basically some DLL crashed inside DllMain and thus the loader lock was abandoned. The injected thread that the debugger creates then gets stuck during its DllMain(THREAD_ATTACH) call. After some time, the operating system uses a "wake debugger" approach and that is what the debugger ends up seeing instead of the original exception. Sounds plausible.
