I am using busybox 1.17.1 and am seeing a hang in hush when a telnet
session is closed without an explicit exit. In that case, hush gets a
SIGHUP, but hush blocks SIGHUP so that it can be handled synchronously
in check_and_run_traps(). The problem is that read_line_input never
returns so check_and_run_traps never gets the chance to see the SIGHUP.
I had to use the following to get read_line_input to return on EOF. Am
I missing anything here?
