Marcus has looked into this problem, see `term/ChangeLog' why this
limit changed.  IIRC there is not a clean way to fix this properly and
the same problem exists on GNU/Linux.  Perhaps I could lookup some IRC
logs in which Marcus described this problem, or even better; Marcus
describing this problem in more detail.

Subject: Screen insert only the first part of a copied text

Package: hurd
Version: 20010718-1

In GNU/Hurd, screen (3.9.9-2) does not paste the complete text from
the buffer. (In GNU/Linux, this problem does not arise with the same
version of screen.)

If you copy a lot of text (for example, the whole screen) with C-a [
and then insert it (with C-a ]), it will only insert about 10 lines
if you paste into programs like bash or vim. Doing "cat" <enter> and
then inserting works as desired, however.

My current libc0.2 version is 2.2.3-7.

I will put a lot of money on the fact that this is tied to the problems
with select/poll.

In fact, it seems to be more of a flow control problem.  defslowpaste 1
helps to work around it.  The limit of pasting text into screen is 300
characters, which is the queue size in term if I am not mistaken.

       slowpaste msec

       Define  the  speed  at  which text is inserted into the current
       window by the paste ("C-a ]") command.  If the slowpaste value is
       nonzero text is written character  by character.  screen will
       make a pause of msec milliseconds after each single charac­
       ter write to allow the application to process its input. Only use
       slowpaste if your underlying  system  exposes  flow  control
       problems while pasting large amounts of text.

Anybody interesting in checking where the problem exactly is, and how it
could be fixed?  Debugging the term on the pty shouldn't be too hard.

Thanks,
Marcus
