[xdebug-general] xdebug using a LOT of memory

I was trying to run pgFouine under xdebug:
http://pgfouine.projects.postgresql.org/

If I run the script outside xdebug, it uses 10 - 12M of ram to do its
job. If I run it under xdebug, it uses in excess of 2G of ram, exceeds
the hard limit on data seg size and is killed by the kernel :)

So, have I found a memory leak that I should help debug? Or is this
expected because xdebug needs this kind of memory to do its work?
