This is not something I'd like to disclose here yet.

It is an application that calls mlockall(MCL_CURRENT|MCL_FUTURE) and
apparently copes with mlockall() returning EPERM (or doesn't even try
it) but can apparently NOT cope with valign() tripping over mmap() ==
-1/EAGAIN.
The relevant people are Bcc:d.
