It isn't that extreme - pointers can make up a significant component 
of data-structures. E.g. any programme that has to store many 
instances of small amounts of data, the pointer size can have a big 
impact on memory usage. If the data is heavily inter-linked, even 
more so.

Whether that's the case for most applications, I do not know however. 
It would though be interesting for someone to go measure this, 
especially in the aggregate.

If this is timesharing, give me my share right now.
