Details:
Haven't tried to setup test case, but when reading wipe_unit() refactoring
from patch #3804 (use unit lists to store drowning units instead of just
having count of them and then rechecking which units they are) it occurred to
me that recursively called wipe_unit() might handle those units calling
wipe_unit() has counted to its 'drowning' counter, meaning that the counter
value is not correct (in practice: counter instructs to wipe units as drowning
ones even after all have been saved)
Using the lists the way refactoring part of patch #3804 does avoids such
problems.
