Subject: [PATCH] worked around tmux not killing jobs launched with run-shell
 -b, fixes #407

upon exiting, tmux < 3.2 waits for jobs ran with run-shell, even those
launched with -b

the workaround consists in still launching "heavy" jobs from the status
line with #() even though it means e.g. battery information will get
updated once per attached client
