[erlang-questions] example of race conditions ?

[Saifi Khan]

Hello:

The last section in Chap 9 (Errors in Concurrent prog) of
Programming Erlang book by Dr. Armstrong, says the following:

"When you combine the Erlang primitives spawn(), spawn_link(),
register() ..., you must think carefully about possible race
conditions.
Write your code in such a way that race conditions cannot happen"

To me, it seemed like an anti-climax of the whole 'lock free prog'
model. Please correct me, if I am wrong.

Can somebody share sample code that *has* race conditions ?

Appreciate a response from the experienced erlangers.


thanks
Saifi.
