PATCH: comp_wrapper

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

The completion function wrapper used to make heap-allocated copies of
the special parameters it ay have to restore. This makes it use
zalloc()ed memory which can then be used directly. In other words: it
makes the wrapper slightly more expensive for functions that make the
special parameters not be restored and makes other functions (the more 
common case) a bit cheaper.

Bye
 Sven
