The new macro PLOCK_DISABLE_EBO may be defined to disable exponential
backoff. This can be useful to more easily spot functions that cause
contention. In this case the CPU will be spent inside the functions
themselves instead of the pl_wait_unlock_{long,int}() functions, making
them easier to spot using "perf top" even if that causes a significant
degradation of the thread scalability.
