[Haskell-cafe] How to check for memory leak.

[zbo]

I was using the code from 

http://www.haskell.org/hawiki/HaskellNewbie_2fTcpIpAndNetworking

It seems to be losing a few Kbytes every call (i use 'top' on linux to check the
RES field value). 

I dont know whether this is a memory leak or just the GC not collecting yet. 
I was just wondering What is the general method to check this.

BTW, I have tried using -prof and -P, but not really able to see anything
suspicious.

Cheers,
