Keep it for 1 day or 10 billion...  The difference is irrelevant.  
(Granted, we only allow you to specify a value between 1 and 7 days, so 
you're unlikely to keep it 10 billion days.)

Live TV is deleted with prejudice when space is required--even before 
Deleted recordings.  It shouldn't bother anyone any more than the 
kernel's use of otherwise-unused RAM for a disk cache does.  As Thomas 
implied, it's just making use of otherwise-unused resources.

Because of this, the current MythTV only ever needs as much space as 
required for the currently-being-viewed session of Live TV (i.e. the 
current program, or, if you just entered Live TV or have been switching 
channels, the part of the current program since you tuned it last).  Or, 
in the case of very long programs, a maximum of 8 hrs of the program.  
Any not-currently-in-progress Live TV recording on an in-use file system 
will be deleted before anything else--that includes the show that just 
finished airing 1 minute ago.
