Since you're pushing that handler onto the cleanup phase, I'm assuming
that you don't mean to send any more data to the client. It sounds like
the buffer isn't getting flushed (though I can't imagine why). Maybe if
you flush it manually? "local $|=1" or something?
I've had this problem in cases where I wanted to fork a long running
subprocess, because the child's STDIN and STDOUT are still pegged to
the browser socket. For a child, it works pretty well to close and
reopen the STD' filehandles to dissociate from the client after the
fork (like running a daemon).
Would that do for what you need here?

...since I don't have a copy of Phaedra on my desk, would you translate
this for me? My French is nowhere near good enough for this one. ;o]
Cheers, and good luck.
