Attached to this message is a file, 'locktcp.c'.  This program, when run
(sometimes multiple runs are necessary to produce the problem) should hang a
Solaris/x86 2.5.1 machine (and possibly other versions of Solaris/x86). Make
sure you pass the IP address and port of a server that puts up a banner
message, such as POP3 or IMAP, as arguments.

The source of the attached program is undisclosed.  The program is available
through other sources and is therefore considered public.

This program appears to be a hackup of Pine's tcp_unix.c file, the one
affecting Solaris/x86 systems.  A workaround for Pine is available:  apply
the following patch to pine3.95/imap/ANSI/c-client/tcp_unix.c before
building.  (This patch will cause bad error messages when connects fail, but
will avoid the problem until it is patched.)
