Description
The GlobalChunkPoolMutex replaced ThreadCritical in JDK-8356173. In NMT, we can unfortunately reach a recursive locking situation in situations when the VM is crashing and NMT attempts to perform a error report. I suggest that we make this particular mutex recursive, until we can resolve the design issues that causes this.

Because of the severity of hanging on crash, I am bumping this to a P3.
