and subject line Bug#676461: fixed in ncurses 5.9-9
has caused the Debian Bug report #676461,
regarding libncursesw5: buggy test causes select() to be used instead of
poll(), making ncurses really slow
to be marked as done.
This means that you claim that the problem has been dealt with.
If this is not the case it is now your responsibility to reopen the
Bug report if necessary, and/or fix the problem forthwith.
(NB: If you are a system administrator and have no idea what this
message is talking about, this may indicate a serious mail system
misconfiguration somewhere. Please contact [email protected]
immediately.)

If i compile the C test myself, adding a printf at the end, ret==0 after the
poll().
The buildds are returning
"checking if poll really works... no"
yet Linux's poll() is fine.
which results in ncurses/tty/tty_update.c using select() instead of poll() for
the main loop,
select() having considerably more overhead.

Closes: 676461
Changes:
ncurses (5.9-9) unstable; urgency=low
.
* New patch 05-fix-poll-test.diff adapted from the 20120608 upstream
patchlevel, correcting the CF_FUNC_POLL test which inadvertently
failed if standard input was redirected, as is the case on the Debian
buildds (Closes: #676461).
* Assume working poll() for the biarch packages where we cannot run the
configure check.
