# Scenario:
#  T1= ({R(Z), R(B), W(Z), W(B)})
#  T2= ({R(C), R(B), W(B)})
#  T3= ({R(B), W(B), C}, HIGH_PRIORITY)
#
# Outcome: T1 must abort, T3 must commit, T2 must commit
#          after T3.
#
# Lock -> {T1 granted, T2 waiting, T3 waiting};
# Then T3 jumps the queue:
# Lock -> {T1 granted, T3 waiting, T2 waiting};
# T3 Rolls back T1
# Lock -> {T3 granted, T2 waiting}
