Broken gen:call/3?

Hi,

This behaviour seems broken to me:

1. One process is linked to another (for supervision reasons), and a  
gen_*:call/2 synchronous request is made from one to the other.

2. The called process crashes while handling the call.

3. gen:call consumes *both* it's own monitor 'DOWN' message *and* the  
'EXIT' message arising from the link

Result: calling process doesn't get 'EXIT' message, and hence doesn't  
know about the crash. It does not then function well as a supervisor...
