-Port to openbsd from <bsd@openbsd.rutgers.edu>. Fix for EOVERFLOW in HPUX 11.11 from <alan.martin@oracle.com> (rt.cpan.org ticket #18932). Module now requires perl 5.6 as suggested by <rdusong@tique.org> (rt.cpan.org ticket #15279). Patches from <reini.urban@gmail.com> for killall to use fname if cmndline is not defined and rename PID_ZOMBIE to PID_ORPHANED under cygwin (rt.cpan.org ticket #14837, #14836). Fixed empty pctmem bug on linux due to change in format of /proc/meminfo (hopefully this format is stable now??).
