-------------------------+---------------------------
 In #2146, joeyh reports that there is a problem with git-annex's use of
 tahoe-lafs, which is that when git-annex invokes {{{tahoe start}}}, then
 if the tahoe process is already running, {{{tahoe start}}} emits some
 error messages on stderr:

 {{{
 joey at darkstar:~/tmp/r>git annex get file
 get file (from tahoe...) STARTING '/home/joey/.tahoe/git-
 annex/ba05f2d7-a100-4ffe-bd82-d2da70f94313'
 Another twistd server is running, PID 26595

 This could either be a previously started instance of your application or
 a
 different application entirely. To start a new one, either run it in some
 other
 directory, or use the --pidfile and --logfile parameters to avoid clashes.

 }}}

 git-annex doesn't want to ignore messages sent to stderr, so instead it
 would like for {{{tahoe start}}} not to complain about an already-started
 process.
