I've found it already. Just notices some zlib lines when building 
solaris version of erlang :)

But anyway second question remains -- should zlib cleanup caller process 
message queue from port's 'EXIT' message?

Are there any useful point of having calling process receive this 
message -- this can be somehow confusing, because if my process wants to 
receive 'EXIT' messages, lookup them in ets table and somehow restart 
died processes(or reopen ports) -- it will be confused receiving message 
from unregistred process, which may be error condition for the program.
