Use them in some existing code that is vulnerable to roundoff errors. The existing constant SBT_1NS is a honeypot, luring unsuspecting folks into writing code such as long_timeout_ns*SBT_1NS to generate the argument for a sleep call. The actual value of 1ns in sbt units is ~4.3, leading to a large roundoff error giving a shorter sleep than expected when multiplying by the trucated value of 4 in SBT_1NS. (The evil honeypot aspect becomes clear after you waste a whole day figuring out why your sleeps return early.) |
