This is not a bug. You have run into filehandle buffering in which the
print is held in a buffer and not displayed on the screen until the buffer
is full or dumped. In the case of printing to STDOUT it is dumped when it
sees a newline. You can turn off buffering using the $| variable. See
perlvar for details.
A gentle tutorial on buffering and how to deal with it in Perl can be found
here:

You are wicked and wrong to have broken inside and peeked at the
implementation and then relied upon it.
