In each case, also give the output of "lsof -n -p 17754" and "lsof -n -p
17752", so we know what 5 and 32 are. 5 is likely to be the read pipe of
the monitor process, so, it's normal to be stuck here. 32 is likely to
be the tap device and it's not normal to be stuck here.
I'll investigate a bit to check if the interface sockets are set in
blocking or non-blocking mode in this version.
