Let U and V be two tasks with distinct home schedulers. Let :math:`B`
be a time point measured by U right before a call to
${../if/release:/name} which unblocks task V which is scheduled on
another processor. Let :math:`E` be a time point measured by V right
after the first context switch after :math:`B`.
While the execution environment is ${.:/environment}, while the semaphore is
a priority inheritance mutex, while exactly task V waits on the mutex,
while the measurement sample is :math:`E - B`, when exactly
${../val/perf:/params/sample-count} samples are collected, the
${.:/limit-kind} shall be ${.:/limit-condition}.
