+# The following shows a limitation of the PUSHJ relaxation code when
+# PUSHJ:s are close, and about 256k away from the section limit: On the
+# first relaxation iteration, the first (or second) PUSHJ looks like it
+# could reach a stub. However, the last PUSHJ is expanded and on the
+# second iteration, the stubbed PUSHJ has to be expanded too because it
+# can't reach the stubs anymore. This continues for the next iterations,
+# because the max stub size is five tetrabytes (4-bytes). At the expense
+# of much more complex relaxation code (including the relaxation machinery
+# in write.c), this is fixable. Anyway, as long as PUSHJ:s aren't closer
+# than five instructions, the existing code does suffice; we're just here
+# to check that the border case *works* and doesn't generate invalid code.
