Description Harald Hoyer 2017-06-30 11:03:09 UTC 
# rpm -q bash
bash-4.4.12-5.fc27.x86_64

# read -N 1 _ < /dev/zero

can only be stopped with SIGKILL(9)
Comment 1 Kamil Dudka 2017-06-30 12:38:46 UTC 
This seems to happen only in the interactive mode.  Batch mode is interruptible:

% bash -c 'read -N 1 _ < /dev/zero' &
[1] 784

% kill %1
[1]  + terminated  bash -c 'read -N 1 _ < /dev/zero'
