Package: procps
Version: 2:3.3.16-5
Severity: normal
It appears watch programs reacts to some signals in undocumented manner.
On receving SIGWINCH (terminal size change) it reexecutes the command and
redraws. That might be problematic, as sometimes watch is to trigger
periodic events, and resizing a window will send big number of signal in
quick succession as the size is changing when the user moves the mouse.
I think using SIGUSR1 (like dd) or SIGINFO (like most bsd tools), could
be a better option.
Or only rerun the command if the window is resized to be bigger than the
current size?
