Exact enforcement of the limits incurs a substantial performance -penalty, although on this 4.7\,GHz \Power{6} system that penalty can be reduced +penalty, although on this x86 system that penalty can be reduced by substituting signals for atomic operations. All of these implementations suffer from read-side lock contention in the face of concurrent readers. -- 2.17.1
