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/send:/name}
which unblocks the waiting 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 a message queue
is empty, while only task V waits on the message queue, 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}.
