Guys thanks so much for taking this discussion further than just the reported
bug that prevented the existing workaround.
I’ve often considered putting this work in myself but wasn’t sure what the
reason was for this not being in bash already and if there was an architectural
difficulty with implementing it. It sounds more like that it just wasn’t
considered as an option rather than there is a problem implementing it.
Given that ksh only ever worked this way (but its shared history performed
flawlessly)l, I would think that the mechanism they used and particularly how
they handled the locking is a good place to start with.
