System: NetBSD 1.6ZK
Architecture: i386
Machine: i386
>Description:
	screen-4.0.2 (from pkgsrc/misc/screen) sometimes
	reports "No more PTYs", even though there should
	be plenty of available PTYs, and other applications (including
	other instances of screen) are able to allocate PTYs.

>How-To-Repeat:
        Install screen.  Use it for several hours, opening and closing
        many windows.  I don't knopw exactly what causes the problem,
        and I have been unable to reproduce it on demand, but my normal
        usage pattern always triggers the problem after several hours.

>Fix:
        The patch in pkgsrc/misc/screen/patches/patch-aa seems to apply
        in the wrong place.  It adds a "#if defined(NetBSD)" section
        below the existing "#if defined(HAVE_OPENPTY)" in pty.c.  Moving
        the NetBSD block above the HAVE_OPENPTY block (instead of below
        it) seems to fix the problem (see the appended patch).  But
        perhaps we should just modify the "HAVE_OPENPTY" block without
        adding a NetBSD block?
