-/** Allows to randomize thread scheduling and insert various glitches across whole program for testing purposes.
-  * It is done by setting up a timer that will send PROF signal to every thread when certain amount of CPU time has passed.
-  *
-  * To initialize ThreadFuzzer, call ThreadFuzzer::instance().
-  * The behaviour is controlled by environment variables:
-  *
-  * THREAD_FUZZER_CPU_TIME_PERIOD_US  - period of signals in microseconds.
-  * THREAD_FUZZER_YIELD_PROBABILITY   - probability to do 'sched_yield'.
-  * THREAD_FUZZER_MIGRATE_PROBABILITY - probability to set CPU affinity to random CPU core.
-  * THREAD_FUZZER_SLEEP_PROBABILITY   - probability to sleep.
-  * THREAD_FUZZER_SLEEP_TIME_US       - amount of time to sleep in microseconds.
-  *
-  * ThreadFuzzer will do nothing if environment variables are not set accordingly.
-  *
-  * The intention is to reproduce thread synchronization bugs (race conditions and deadlocks) more frequently in tests.
-  * We already have tests with TSan. But TSan only covers "physical" synchronization bugs, but not "logical" ones,
-  *  where all data is protected by synchronization primitives, but we still have race conditions.
-  * Obviously, TSan cannot debug distributed synchronization bugs.
-  *
-  * The motivation for this tool is an evidence, that concurrency bugs are more likely to reproduce
-  *  on bad unstable virtual machines in a dirty environments.
-  *
-  * The idea is not new, see also:
-  * https://channel9.msdn.com/blogs/peli/concurrency-fuzzing-with-cuzz
-  *
-  * Notes:
-  * - it can be also implemented with instrumentation (example: LLVM Xray) instead of signals.
-  * - we should also make the sleep time random.
-  * - sleep and migration obviously helps, but the effect of yield is unclear.
-  *
-  * In addition, we allow to inject glitches around thread synchronization functions.
-  * Example:
-  *
-  * THREAD_FUZZER_pthread_mutex_lock_BEFORE_SLEEP_PROBABILITY=0.001
-  * THREAD_FUZZER_pthread_mutex_lock_BEFORE_SLEEP_TIME_US=10000
-  * THREAD_FUZZER_pthread_mutex_lock_AFTER_SLEEP_PROBABILITY=0.001
-  * THREAD_FUZZER_pthread_mutex_lock_AFTER_SLEEP_TIME_US=10000
