Is this a bug?

[Rob Landley]

If I do the following:

dbclient user at system "sleep 10& echo hello"

It should return right after printing hello, but it doesn't.  It waits until 
the child process exits.

This is a known, longstanding but in OpenSSH on Linux.  It doesn't do this on 
OpenBSD (the OpenSSH developers insist that it must therefore be a Linux bug, 
but the Linux developers I talked to wondered what they were drinking, if I 
recall correctly from when I asked in 2001.)  An xterm won't do this, telnet 
won't do this...  Just OpenSSH on Linux (not OpenBSD).  And now dropbear.

Is dropbear intentionally copying this bug?
