Description

This test is flaky, I can easily make it fail:

$ ./TFileTransportTest
Running 5 test cases...
TFileTransportTest.cpp(289): error in "test_flush_max_us1": check delta < max_allowed_delta failed [17031 >= 15000]

*** 1 failure detected in test suite "TFileTransportTest"
$ ./TFileTransportTest
Running 5 test cases...

*** No errors detected
$ ./TFileTransportTest
Running 5 test cases...

*** No errors detected
$ ./TFileTransportTest
Running 5 test cases...
TFileTransportTest.cpp(339): fatal error in "test_noop_flush": critical check delta < 2000000 failed [3000242 >= 2000000]

*** 1 failure detected in test suite "TFileTransportTest"
$ ./TFileTransportTest

TFileTransportTest.cpp(339): fatal error in "test_noop_flush": critical check delta < 2000000 failed [3000137 >= 2000000]

Seems like this has hit a couple times in Jenkins already.
