I saw the problem with libkse earlier. I haven't tested again, but it
looked the same as libthr.
Basically, dup2() fails, for reasons unknown (and ak03, for one, thinks
the bug is libc_r's) with libc_r, causing it not to call
konsole_grantpty. When that happens, ttyname() called later works. With
libthr, the dup2() doesn't fail, konsole_grantpty gets called, and
ttyname() fails.
This happens only one time for each pty/tty.
