// The ASAN test JVM is pinned to -Xmx512m (see ConfigurationPresets.kt)
// to keep the heap below ASan's shadow-memory region. Without forking,
// Gradle reuses one JVM for the whole suite, and per-test allocations
// (JFR recordings, JMC object models) accumulate until it OOMs late in
// the run even though every individual test passes. Restart periodically
// to bound cumulative heap growth.

// TSan + JVM integration tests are incompatible: the profiler's signal
// handlers (SIGPROF at 1ms) are TSan-instrumented; when a signal fires
