Local fix
Problem summary
When using Async GLVM, and a write to the remote glvm site fails, certain timing of I/O during the error handling path can result in the local node to crash with the stack trace above.
Problem conclusion
Correct some logic with reguards to locking to not crash in this scenario
Temporary fix
