I've had the same issue (for the same reason :-) ) once or twice before. 
Usually, running hg verify on the repository will tell you the first 
corrupted revision (usually the one you were pulling when running out of 
space/quota), and you can then clone everything else, which gets you 
back where you started.

While it may be a good idea to clean up testboard once in a while (I am 
not sure how well hg scales to thousands of heads), we should try to 
archive the changesets somewhere. Otherwise it will be impossible to 
read old threads on the list, which sometimes refer to them.
