   Thanks! I spent some time tracing this further. From the current source, I 
couldn't find a path where netvc->thread and nh->thread diverge,they appear to 
be assigned together during initialization and I couldn't find any later 
reassignment.
   
   Looking at @wuxcer's latest crash log, the mitigation check if (this->thread 
!= this_ethread()) appears to have passed before MUTEX_TRY_LOCK(nh->mutex) 
failed, which made me realize my original explanation is probably incomplete.
   
   Could you point me to the scenario you had in mind where the NetVConnection 
thread differs from the NetHandler thread? I suspect I'm missing some execution 
path or historical context, and I'd like to understand that before updating the 
scheduling target.
