BTW During Fuse4X development I found it useful to define -DQUEUE_MACRO_DEBUG for Debug builds. This flag forces setting TAILQ prev/next links to NULL and if your code has a bug (e.g. incorrect queue handling) then you'll get a SIGSEGV, otherwise your code will continue to use incorrect pointer and it might be harder to discover the bug.
