ssh2 2.4 hangs when used with pipe

[Ric Anderson]

On solaris 7, using ssh.com's ssh2 version 2.4.0, I consistently
get hangs when doing
        ssh somehost somecommand | something that exits before ssh2
As a test case, I used
        ssh somehost -n last | true
which never returns to a command prompt.  

It appears ssh2 completely ignores SIGPIPE, proceeds to burn
cpu cycles after "true" exits.

Has anyone else seen this or is something amiss with my build?
