2.20.  RHEA-2009:1294: pth

A new package, pth, is now available for Red Hat Enterprise Linux 5.
Pth is a very portable POSIX/ANSI-C based library for Unix platforms which provides non-preemptive priority-based scheduling for multiple threads of execution ("multi-threading") inside server applications. All threads run in the same address space of the server application, but each thread has it's own individual program-counter, run-time stack, signal mask and errno variable.
This new package is required by the new gnupg2 utility. GnuPG 2.0 is a newer version of GnuPG, a tool for secure communication and data storage. GnuPG 2.0 derives from a different design philosophy and includes additional support for S/MIME. (BZ#484189)
Anyone wishing to use GnuPG 2 is advised to also install this new package.
