Spurious write permission error

[Clive]

Until recently I have routinely run 2/3/4 instances of gip from one 
Linux Terminal box with no problems - open multiple tabs in one session 
and run separate downloads in each, sometimes all radio or TV and other 
times a mix. I have not encountered a conflict with the download history 
getting corrupt. I have always refreshed the cache in one before running 
multiple. I know this does not help much but it does share an experience.

However, I have recently started getting download failures when running 
parallel downloads; one of the pair (and not always the first or second 
to start) will fail part way through with a time-out/not responding 
error. I do not think this is a download cache problem as at the point 
of failure neither has completed. I delete the partial and start again, 
it restarts without a --force so I guess the download history has not 
been written.
