| Pressing the stop button in the browser while doing an upload to
perlbal consistently kills perlbal with my set up. The error in
/var/log/messages is:
Jul 7 14:12:18 baker perlbal[12535]: crash log: Can't use string
("c") as a SCALAR ref while "strict refs" in use at
/usr/lib/perl5/site_perl/5.8.5/Perlbal/ClientProxy.pm line 923.
It looks like this is because of line 947 of ClientProxy.pm, it's
unshifting a string instead of a reference to a string into the
buffer.
I made this change and it stopped dying, but I got an error about an
undef $fh from AIO instead.

Was that intentional?
