Hi!

This patch looks like a good solution for a pain in the ass, I'm too for
this patch to be committed.
Have looked through the code and agree with Andrei, the code looks good.
Just a suggestion - maybe it is worth adding a function for detaching the
segment,
for cases when we unload and/or re-load the extension?
