This has been talked about on HP/UX platform as well.  The feeling is that
sigaction() may be a better solution.  However, nothing has appeared in
the OpenBSD tree in regards to that solution yet.

As for the truncation problem.  It was introducted in around 2.1.1p4 in
hopes to deal with a problem with linux's 'select()' function.  It was
reverted in 2.3.0p2 snapshot because it was learned scp was effected by
it.
