+It seems that somehow it is failing to set environment variables. Eg,
+`GIT_INDEX_FILE` is what makes git use `.git/annex/index` and if it was not
+set it would behave as you describe.
+
+This strongly suggests that there is a bug in the compiler/libraries.
+
+Here is a small test program:
+
+	import System.Environment
+	import System.Process
+	
+	main = do
+		let p = (proc "sh" ["-c", "echo testing: $TEST"])
+		let p' = p { env = Just [("TEST", "foo")] } 
+		withCreateProcess p' $ \_ _ _ pid -> waitForProcess pid
+		setEnv "TEST" "bar"
+		withCreateProcess p $ \_ _ _ pid -> waitForProcess pid
+
+If run with "runghc foo.hs", that should output "testing: foo" and then 
+"testing: bar".
