Theres a bug in timemachine causing a click after the pre-record buffer.

Heres a diff i use, which gets rid of the click, possibly introducing
another bug - there must be a reason for having the '+ 1' in the loop
which i cant see by looking in these 5 lines...

Ive sent an email to Steve, but should perhaps send this to linux-audio
as well...
