Comment #6 on issue 3498 by rydier: remove:ifAbsent: in linked list leads
to interruption/sync problems
http://code.google.com/p/pharo/issues/detail?id=3498
For the record, it was rewritten to accept regular objects as well as links
as arguments (in which case a ValueLink for the object is created with
add/found and removed with remove)
removeLink:ifAbsent: is exactly the same as remove:ifAbsent: in Squeak
The reason I did not add the ifAbsent: block to the removeLink: call in new
remove:ifAbsent: was pure ignorance, I was not aware LinkedLists methods
were supposed to be thread-safe, for instance add:after: is not, neither in
Pharo nor Squeak.
The version currently in Pharo (without ifAbsent:) is perfectly valid if
thread-safeness is not a criterion.
