>Description:

The user ppp will at times use as much CPU as FreeBSD will give it.  I noticed
very early this morning when I turned the monitor on, and wondered why my
'make world' was still running (I had started it about 12 hours earlier, and
it was only about 20% done... my machine is not this slow :-).  I fired up a
top, and noticed ppp using practically all my CPU.  I killed it (it wouldn't
respond at the telnet port), restarted it, and did a few things on the net.  I
let it time-out again, and the ppp process started using all the CPU again
(and I killed it again and restarted it... now I'm writing this).  I noticed
this message on the console when I re-started it:

rtinit: wrong ifa (0xf217c980) was (0xf217cd00)

but it otherwise seems to work properly.  (that message or similar pops up
sometimes when ppp starts, but does not appear in the ppp source).

>How-To-Repeat:

I don't know, it seems to happen without much pattern.  It will be fine for
days, then it's eating too much CPU.

 A -11 should work too.  Other signals are "pended" and are actually
 actioned in the top level loop.  It appears that it was possible to
 get stuck in a non-top-level loop at the time (spinning - hence the
 CPU time).
 
 Some work on these pending signals was done between -GAMMA
 and -RELEASE.  I believe the problem was fixed.  I'm going to close
 the pr, so if you encounter the problem again, please submit another pr.
 
 Thanks.
