Thanks. I've applied this manually, since it happens that I am currently
working on splitting the dlopen(3) page into smaller pieces. So, it will
be a short while before your changes in this patch are released.

You might also want to check the thread safety of dlinfo(), dlmopen(),
and dladdr1(), since man pages for those functions will, I hope, soon
appear.

Cheers,

Michael
