scancel -s SIGINT

directs slurm to give the processes in the batch job that signal. When
GROMACS gets it, it writes a checkpoint and does an orderly exit at the
next neighbour-search step.

Using mdrun -maxh 24 is a useful way to have mdrun know in advance that it
should stop before 24 hours, which might be when a job scheduler starts
sending signals.
