 .SH BUGS
+The macros
+.BR TAILQ_FOREACH ()
+and
+.BR TAILQ_FOREACH_REVERSE ()
+don't allow
+.I var
+to be removed or freed within the loop,
+as it would interfere with the traversal.
+The macros
+.BR TAILQ_FOREACH_SAFE ()
+and
+.BR TAILQ_FOREACH_REVERSE_SAFE (),
+which are present on the BSDs but are not present in glibc,
+fix this limitation by allowing
+.I var
+to safely be removed from the list and freed from within the loop
+without interfering with the traversal.
