The shell should be blocked on read of standard input unless it is
actively reading a command.  Do you mean you're interacting with a
shell that's running on this embedded system?

Do you have something like strace you can connect to the shell with to
see what system calls it is making?

Make sure you don't have SHARE_HISTORY or INC_APPEND_HISTORY or
INC_APPEND_HISTORY_TIME set -- but even those I'd only expect to be
examining the history when the shell is actively doing something.

Zsh does create and delete a lock file every time it needs to examine
the history.  In a recent shell you can try HIST_FCNTL_LOCK to see if
that avoids the lock file creation.
