Good question. The ansewr is yes, and everything I mentionned applied.

As for the performance issue, I did some profiling, and it couldn't see 
any difference in execution time between mmap-ed and non mmap-ed output 
unit. This is mainly because pre-connected units are formatted, and 
formatting time is what takes all the time.

So, I'm now fully convinced (I'l still be glad to have your opinion, of 
course) we need such a patch for non mmap-ed preconnected units. Will 
post it on Monday.
