  GStreamer | gstreamer (core) | Ver: HEAD CVS
           Summary: use string pools to lower number of relocations
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED

See http://0pointer.de/blog/projects/string-pools.html for code example.

Here we could use it right away and would ave around 50 relocs.
gstreamer/gst$ grep -Hn "gchar \*.*\[\]" *.c
gstinfo.c:646:  static const gchar *levelcolormap[] = {
gstplugin.c:96:static const gchar *valid_licenses[] = {
gstquark.c:28:static const gchar *_quark_strings[] = {

Unfortunately it won't work for gstenumtypes.c.

With some effort (split into separate arrays) more could be saved on:
GstEventQuarks, GstFormatDefinition, GstMessageQuarks, GstFlowQuarks,
GstQueryTypeDefinition, GstStructureAbbreviation

One can check the number of relocations
readelf -d .libs/libgstreamer-0.10.so | grep RELCOUNT
which for me right now is '1036'.
