# Repeats the execution of the $2 mode $1 times. Defaults are debug and 1000,
# for $1 and $2 arguments, respectively.
#
# This is useful for coaxing hard bugs that only arise with rare thread
# interleavings.
#
# Should only be run in the project directory root.
# 
# Currently this runs the mpmc-test.exe, which is most susceptible to those
# kinds of bugs.
