/*
 * Program to test the performance of gtk_tree_store_prepend vs.
 * gtk_tree_store_append. Has its own timer, or use time(1) to get a
 * better idea of how much CPU time it's really taking.
 *
 * Compile it with something like:
 *   gcc `pkg-config --cflags --libs glib-2.0 gtk+-2.0` gtktreeview-perf.c
 *
 * Usage: ./a.out [p]
 *
 * The 'p' flag enables the much faster prepend method.
