I can reproduce this if the remote dir is big enough, just the numbers
are different.  In one dir with < 500 files it works fine, in another
dir with > 3000 files I get between 70 and 120 repetitions.

And I have another weird effect:

  $ lftp server
  lftp server:>cd large-dir
  cd ok, cwd=/large-dir
  lftp server:/large-dir>ls | less
  ls: less: Permission denied
  lftp server:/large-dir>ls | less
  ls: less: Permission denied
  lftp server:/large-dir>ls | less
  ls: less: Permission denied
  lftp server:/large-dir>ls | less
  ls: less: Permission denied
  lftp server:/large-dir>ls | less
  [...works...]

I can reproduce this with a very high probability.  4 or 5 or 10 times
in a row it fails.  Then, as soon as the first `ls | less' call
succeeds, all subsequent calls succeed as well.  Calling just `ls' once,
helps, too.

Unfortunately I can't reproduce it when running under strace.  In that
case `ls | less' already succeeds the first time, every time I try it :(
