-# In order to make the handle_signal() stuff above work, we have to execute

-# executed command finishes. This, however, introduces another issue regarding
-# how bash's wait works. Quoting:
-#
-#   When bash is waiting for an asynchronous command via the wait builtin,
-#   the reception of a signal for which a trap has been set will cause the wait
-#   builtin to return immediately with an exit status greater than 128,
-#   immediately after which the trap is executed.
-#
-# In other words - every time we propagate a signal, wait returns with
-# 128+signal, so we have to wait again - repeat until the process dies.
