Greetings. I attach the code sample, which expected behaviour is:
1. to periodically restart thread, which executes «sleep 1s» with system* call; 2. and then to check if it should repeat the execution. The flag, which controls that re-execution is managed by another thread through atomic-box primitive. The code does not run as expected: the sleep executing sleep starts once, and change seems to remain invisible to main thread. The code works as expected, when: 1. (sleep 1) is used instead (system* "sleep" "1s"); 2. running the code on x86_64 cpus. The use of affinity mask taskset 0x01 guile test.scm does not help. - MB. Respectfully P.S.
