But surely ardour does look ahead in the timeline, to open()/seek()/read()
a new file a few seconds before the data is actually required ? Or does
it keep all files open all the time ?

Suppose you have a timeline like ABCACDBABCCA where each char is a
very short region (maybe just a fraction of a second) and the actual
char refers to the file that region is read from. For example in 'CC'
near the end the first C could be a few seconds of music ending in
silence and the second C a repeat of 400 ms of the end of the first
(e.g to remove a cough or the sound of a score page being turned),
while both are just a few seconds away from the earlier occurences
of C. Would each of the regions be handled independent of any others ?
