Description

This issue is mainly about memory optimization
It comes from profiling a real world (complex) application on mobile & desktop
Optimizations will also apply to desktop

mx.binding.Binding use exception/error as control flow.
While it's perfectly valid, it's seems to be very bad from the memory allocation side (as reported by Scout)

Will provide a patch as a basis for discussion.
