There are lots of ways of making things much faster than any new malloc 
library ever could.

For example there are many KDE programs that take an O(N^2) amount of time to 
do some work dependant on the data size.  For example consider the amount of 
time taken to display a message in kmail, for messages that are <50K in size 
the time is quite reasonable, but for megabyte messages it's terrible.  This 
is something that a better malloc library might alleviate, but it needs some 
better algorithms in the core code to solve it.

Another example (which I haven't tested recently - it may be fixed but I 
doubt it) - try a ftp:// URL where there are thousands of files in the 
directory, it's an easy way of making what is essentially 100KB of text cause 
Konqueror to allocate 50M of RAM and only avoid thrashing VM because it's 
using all the CPU time.

I've been thinking of working on these issues for years, but I've always had 
other things to do.

PS  Before calling someone a lamer I generally do the following:
Grep for their name/email address in /var/lib/apt/lists/*
Search sourceforge for their name.
Search advogato for their name.
Do a google search on their name.

That avoids the potential embarassment of calling someone a lamer only to 
discover that they contribute more than me.

If you send email to me or to a mailing list that I use which has >4 lines
of legalistic junk at the end then you are specifically authorizing me to do
whatever I wish with the message and all other messages from your domain, by
posting the message you agree that your long legalistic sig is void.
