Wow, that's quite an improvement. libgnome for example:
Run gconftool-2 in a for loop:
real    1m31.711s
user    0m56.800s
sys     0m5.952s

Feed the whole ${schemas[ ]} array to gconftool-2:
real    0m51.198s
user    0m28.254s
sys     0m3.660s

The same, now with the patch:
real    0m8.158s
user    0m4.104s
sys     0m0.492s

This is a gigantic speed improvement. This is tested on an Athlon XP
2800+ with 1GB RAM on ext3. With the slowest result, I can even see
kjournald and gconftool-2 hanging in D status while running top.
