[Swift-devel] hangs in nmi build and test at first site selecting stage

[Ben Clifford]

Two times in the past few days (out of 30 or so build/tests x about 120 
runs per build/test) runs have hung at the initial site selection stage 
for the first job. I haven't investigated in greater depth than this. My 
gut feeling, though, is that its probably still some funny behaviour 
related to rate limiting. Sometime in the next few days I'll see about 
running a few thousand tests with more debugging info to see if I can get 
more info...
