Comment (by zooko):

 Replying to [comment:4 gdt]:
 > This strikes me as messing up normal behavior to accomodate a broken
 caller.  starting a process (of which there can be only one) when it is
 already running is actually an error.

 I disagree. There is no requirement for the caller to refrain from calling
 {{{tahoe start}}} when the process is already running. The recommended way
 to ensure that a process is running is to call {{{tahoe start}}}. Why
 should it be otherwise?
