+// you should avoid using this pass if they mean something else for your
+// language.
+//
+// All methods assume that the pointer is not NULL, if it is then the returned
+// allocation size is wrong, and the result from checkLimits is wrong too.
+// It also assumes that pointers are valid, and that it is not analyzing a
+// use-after-free scenario.
+// Due to these limitations the "size" returned by these methods should be
+// considered as either 0 or the returned size.
+//
+// Another analysis pass should be used to find use-after-free/NULL dereference
+// bugs.

$RANDOM is a bashism, it has been replaced with portable code.
Also, the randomly generated port is checked to make sure it's not already
in use.
