Ok, so if I understand correctly, one of two things must happen when I call 
ast_write() from my application:

1) The channel makes a copy of the frame for sending later, and takes charge 
of freeing the copy.

2) ast_write() is synchronous and the frame is no longer needed once it 
returns.

Which is it?

Either I'm getting it all wrong, or I have an even bigger problem than I first 
thought. And my code is largely inspired from Sergio's on sip.fontventa.com 
so we'd be two. ;)
