Preventing/handling space leaks

[Henk-Jan.van.Tuyl]

L.S.,

Does anyone know about documentation (preferably on the Web) on how to prevent/find/remove space leaks?
Are there any differences between Hugs and GHC or any other Haskell platform, regarding space leaks?

I read some discussions about why not everybody uses Haskell; it looks to me, that the problem of space leaks is a very good reason to not use Haskell for commercial applications. Java, for example, does not have this problem.
