Well, as I see it the problem with optimising malloc for startup times is
that according to my profiling, at most 1% time of total is spent in
malloc during startup of say gedit, while in real use - I opened a 300KB+
text file and page-downed to the end - the use grew to 3% of time. 

But this is on admitedly on solaris, not linux.
