AddressSanitizerInterface.GetOwnershipStressTest affects the run-time of other tests

Reproduce (x86_64 linux): 

% ./bin_linux/asan_test64 --gtest_filter=AddressSanitizerInterface.GetOwnershipStressTest:AddressSanitizer.OOB_*
2>&1 | grep OK
[       OK ] AddressSanitizerInterface.GetOwnershipStressTest (3854 ms)
[       OK ] AddressSanitizer.OOB_char (5224 ms)
[       OK ] AddressSanitizer.OOB_int (5208 ms)


./bin_linux/asan_test64 --gtest_filter=AddressSanitizer.OOB_* 2>&1 | grep OK
[       OK ] AddressSanitizer.OOB_char (760 ms)
[       OK ] AddressSanitizer.OOB_int (794 ms)

I suspect that multiple mallocs in AddressSanitizerInterface.GetOwnershipStressTest
interfere with the death tests in AddressSanitizer.OOB_char somehow.

Simple experiment: 

TEST(AddressSanitizer, MultipleDeathTest) {                                       


  for (int i = 0; i < 100; i++) {                                                 


    EXPECT_DEATH(exit(1), "");                                                    


  }                                                                               


}                                                                                 





TEST(AddressSanitizer, MultipleDeathAndMallocTest) {                              


  free_aaa(malloc_aaa(1 << 29));                                                  


  for (int i = 0; i < 100; i++) {                                                 


    EXPECT_DEATH(exit(1), "");                                                    


  }                                                                               


}                

The first test runs < 2 seconds, the second test runs 10 seconds.
Looks like the cost of the death test depends on the amount of reserved memory. 
Oh my...
