linux lsof hangs run-command-shim in function check_binary_write_lock

[andlic45]

run-command-shim shell ( function check_binary_write_lock ) script uses "lsof" to find some locking info, see below section of the code.
lsof could hang due to various reasons and so the calling script run-command-shim, one example is with unresponsive filesystems like NFS mounts.
The solution may be to use other non-blocking ways to find required info or simply remove this verification.
Thank you

check_binary_write_lock() { set +e # disable exit on non-zero return code local retry_attempts=0 while (( retry_attempts < 10 )); do lsof_result="$(lsof -F ac ${bin})"
