Is detection of open by multiple processes/threads possible?

[Shane Hansen]

I'm working on a deployment model where I spin up a new process before killing off the old process. I understand ybc doesn't support being opened from multiple processes but I'm wondering if there is a way that I can detect if a cache file is currently open before opening it in the new process.

If not, I'll probably just build my own signaling mechanism. I know sqlite has similar restrictions but does manage to avoid corruption.

Thanks!
