            Bug ID: 1229494
           Summary: pmprintf shouldn't use /var/tmp files
           Product: Fedora
           Version: rawhide
         Component: pcp
          Assignee: nathans@xxxxxxxxxx
          Reporter: fche@xxxxxxxxxx
        QA Contact: extras-qa@xxxxxxxxxxxxxxxxx

libpcp/src/util.c's use of /var/tmp/$FILEs for buffering each pmprintf call is
inefficient (leads to excess syscall & physical disk traffic).  On linux and
probably elsewhere, it could easily use fmemopen(3) or open_memstream(3)
instead.
