bug#15311: 24.3; Infinite loop in x_make_frame_visible

[Andreas Schwab]

In a long running Emacs session creating a new frame causes
x_make_frame_visible to hang while waiting for FRAME_VISIBLE_P (f), with
input_signal_count never changing (XTread_socket is never called).  I
can force breaking out of the loop from the debugger and everything
continues to work, including the newly created frame (but the problem
reappears with every new frame).  The syscall trace shows these calls
repeated indefinitely during the hang:

poll([{fd=4, events=POLLIN|POLLOUT}], 1, 4294967295) = 1 ([{fd=4, revents=POLLOUT}])
writev(4, [{"+\10\1\0", 4}, {NULL, 0}, {"", 0}], 3) = 4
poll([{fd=4, events=POLLIN}], 1, 4294967295) = 1 ([{fd=4, revents=POLLIN}])
--- SIGIO {si_signo=SIGIO, si_code=SI_KERNEL} ---
recvfrom(4, "\1\1\24\240\0\0\0\0+\0\200\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 4096, 0, NULL, NULL) = 32
recvfrom(4, 0xc21f34, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)
recvfrom(4, 0xc21f34, 4096, 0, 0, 0)    = -1 EAGAIN (Resource temporarily unavailable)

Andreas.

Do you still see this problem in `emacs-24' or in `trunk'?

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
