[Fkt-devel] implementing fut_flush

[François Trahay]

Hi,
One eztrace user has reported a feature-request in eztrace that needs to be 
implemented in fxt. For now, when the event buffer is full, fxt stops recording 
events. The trace may thus be incomplete.
I have implemented an fut_flush function that can be called in this case for 
flushing the buffer to disk, allowing to record the remaining events. This 
features has to be explicitly requested (by calling enable_fut_flush() ) since 
fut_flush has a significant impact on performance when it is called.
Can i commit this to fxt repository ?

François
