Nope, this is a known issue.  It happens a lot on Test Grid, where  
there are nodes which are offering storage service but which  
disconnect abruptly without saying goodbye or which take ages  
(minutes) to respond to your requests.  I encounter it frequently  
because my blog is stored on Test Grid.  It doesn't happen very often  
grids with higher-quality storage servers.  Here are some probably- 
relevant tickets: #193, #253, #287, #436, #521, #573.

I would love it for this to get fixed.  Maybe someone wants to  
contribute to Tahoe-LAFS by fixing this issue?
