Well... in fact it is a solution. Maybe you don't like it, but that is
another issue.

Keep in mind, though, that moving towards a single-threaded solution does
not eliminate the possibility of the OLSR main process getting blocked by
one of the plug-ins. The registered plug-in function may, after being
called, never return (or return only after a very long time).

In fact, switching from a multi-thread solution towards a single-threaded
solution is to some extent the same as exchanging the OS-scheduler for the
OLSR-scheduler.

Windows 3.1 used so-called co-operative multitasking. There was only one
thread, issued by the OS. Applications registered with the OS their
functions to be called. Those functions had to return quickly otherwise the
OS would hang. We've come a long way since then.
