so, to ensure gs terminate is called,
otp:start_link | erlang:link should be followed by
can we say that?
> most of the questions you ask come from not properly
understanding the signals in Erlang, and how trapping exits affects
them. I recommend reading possibly
http://learnyousomeerlang.com/errors-and-processes for this.
well you see I link only from supervisors via otp:start_link, spawn
non-otp stuff and otp:start otp children from non-sups, relying on
timeouts to tell that something went wrong. crashes do not really
cause havoc in this scheme so I did not pay much attention to linking.
I assumed that OTP links traps exits by default. Thank you for clarifying this!
Thank you very much Fred.
