So I been using async stuff and a global connections seq for a while in
production and stuff. I don't have any issues with this, but it appears to
cause a warning.
What can I do about it? Should I silence the warning? What kind of issues
should I expect? Under my impressions is that async stuff should all be using
the same thread so sharing things like seq should be fine?
Is there a better way to write this code?
nim-1.0.0/lib/pure/asyncmacro.nim(271, 31) Warning: 'cbIter' is not GC-safe
as it accesses 'connections' which is a global using GC'ed memory [GcUnsafe2]
