Auto merge of #109432 - flba-eb:108594_forkspawn_exponential_backoff, r=workingjubilee
QNX Neutrino: exponential backoff when fork/spawn needs a retry Fixes #108594: When retrying, sleep with an exponential duration. When sleep duration is lower than minimum possible sleeping time, yield instead (this will not be often due to the exponential increase of duration). Minimum possible sleeping time is determined using `libc::clock_getres` but only when spawn/fork failed the first time in a request. This is cached using a LazyLock.
