[Dojo-interest] addOnLoad: exception preventing execution of all remaining functions in the addOnLoad queue

A problem that has been bothering me for a while.
I have a lot of page initialization functions being added to
However, if one of these functions fails / throws an exception, all the
remaining functions in the addOnLoad queue are simply not executed.
var pseudo = null;
pseudo.focus(); // this will obviously fail with a nullpointer exception
In this example, A will be executed correctly, it then proceeds to B which
fails, and C is never executed.
Sure, you could argue that I could catch exceptions in the functions I
supply to addOnLoad, but I'm working in a large organization where I can't
control what everyone else supplies to addOnLoad. Effectively someone could
brick my addOnLoad calls from working by supplying some code that'll blow up
- effectively bricking all the remaining queued addOnLoad functions.
Is there a nice way out of this problematic situation?
A solution could be to run seperate addOnLoad queues / groupings, that would
not affect eachother.
But this seems like a big change to the insides of Dojo...Can anyone come up
with another more lightweight approach to circumvent this problem?
Thanks in advance ;-)
