Description

If you have a bad, non-working but active, or non-existent internet connection, mc halts during startup for several seconds (sometimes minutes).

With strace I could get the following when the halt happens:

futex(0x7fcccbd49324, FUTEX_WAKE_PRIVATE, 2147483647) = 0
openat(AT_FDCWD, "/etc/resolv.conf", O_RDONLY|O_CLOEXEC) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=688, ...}) = 0
read(3, "### /etc/resolv.conf is a symlin"..., 4096) = 688
read(3, "", 4096)                       = 0
close(3)                                = 0
socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 3
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = 0
sendto(3, "\2\0\0\0\r\0\0\0\6\0\0\0hosts\0", 18, MSG_NOSIGNAL, NULL, 0) = 18
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}], 1, 5000) = 1 ([{fd=3, revents=POLLIN|POLLHUP}])
recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="hosts\0", iov_len=6}, {iov_base="\310O\3\0\0\0\0\0", iov_len=8}], msg_iovlen=2, msg_control=[{cmsg_len=20, cmsg_level=SOL_SOCKET, cmsg_type=SCM_RIGHTS, cmsg_data=[4]}], msg_controllen=20, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 14
mmap(NULL, 217032, PROT_READ, MAP_SHARED, 4, 0) = 0x7fcccaf32000
close(4)                                = 0
close(3)                                = 0
socket(AF_UNIX, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 3
connect(3, {sa_family=AF_UNIX, sun_path="/var/run/nscd/socket"}, 110) = 0
sendto(3, "\2\0\0\0\4\0\0\0\r\0\0\0linux-laptop\0", 25, MSG_NOSIGNAL, NULL, 0) = 25
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP}], 1, 5000

The same trace is reproducible.
