the "price" of a context switch/function call

[Ralph DiMola]

Mark talked about the cost of context switching at RR14. The default "by
value" parameters in a call will be "by reference" until data has changed.
Only then will a local copy be created. So... If you pass a large array only
the keys that have been changed(if any) are allocated new memory and copied.
Don't remember the initial version for this new context switching
implementation.
