+Subject: [PATCH 25/67] xl: move freemem()'s "credit expired" loop exit
+
+Move the "credit expired" loop exit to the middle of the loop,
+immediately after "return true". This way having reached the goal on the
+last iteration would be reported as success to the caller, rather than
+as "timed out".
