Why is this allocated dynamically? This structure is not very large, and a hole in 
thread_struct isn't that big of an issue - compared to additional fragility 
introduced by the (mostly untested by normal apps) dynamic allocation here ...

I don't mind the introduction of the sub-structure in itself, but please embedd it 
in thread_struct.

Thanks,

	Ingo
