Recently I noticed a problem in the konqueror preloading behaviour. When 
browsing the web, If I open 10 tabs (or even more), I have a memory 
consumption that can reach 20 - 30 MByte. This is good. The problem is when 
the konqueror gets closed. In my local installation it is kept in memory for 
preloading. This is a problem becouse I have a preloaded konqueror that uses 
lots of memory. If I kill it the used memory goes down of 20 - 30 MBytes.

I got  a look at the code and the problem seems to be in konq_mainwindow.cc
in the current_memory_usage() function. 

In fact even with a konqueror with 20 - 30 tabs sometimes it returns a memory 
usage of 9MBytes. And since with the current behaviour we don't keep a 
konqueror into memory if this value is greater than 16MByte, our konqy is 
kept for preloading.

This is the output:
konqueror: Memory usage: 8808872(startup=3229960)

More precisely I have:
mallinfo:  m.hblkhd=229376 m.uordblks=8579496
where m is a mallinfo object.

I'm not very confident with the mallinfo stuff, so I ask you help.

Another question. Is it possible to reset the konqueror every time we want to 
keep it for preloading? IMHO this should be the correct behaviour.
