Queue between two machines and problem of hanging on windows

I made one code run on windows and another on linux. they have a shared folder where the database located via network share. two problems I'm facing. the queue isn't properly updated. often when the one waiting for message is running in while loop, and I run the put operation. nothing pops up. I used block=false to test this. because without that I have another problem on windows. the get operation seems to become unresponsive. I have to press ctrl+c numerous times to break.

I wonder if both or one caused by locks. problem also seems to happen with file based (but I haven't tested that extensively to be sure)

ubuntu 18 (put) and windows 10 get, shared folder on ubuntu. Using python3.6 on both

@allusernamestakenexceptthis Can you please run the benchmark script on you share? Any more info about the network share and the trace after aborted?
