Description

The following tests are taking quite some time to succeed:

• MemoryManagerSharedResourcesTest::testLastReleaseReleasesMemory
• MemoryManagerSharedResourcesTest::testPartialReleaseDoesNotDisposeResource
• MemoryManagerSharedResourcesTest::testPartialReleaseDoesNotReleaseMemory

This is due to the fact that MemoryManager::verifyEmpty() causes exponentially-increasing sleep times in UnsafeMemoryBudget::reserveMemory.
