Ref: #4833

@monnerat, does this make things any better?

Yes, it does and stops hanging test 670. This is very near what I tried myself while investigating. However I thought of a more elaborate solution (checking read and write pause state change separately) for a final commit.
Thanks.

@monnerat, are you saying you want to do it differently or that you'd be positive to land this PR?

This is already an improvement, so you can commit it :-)
