> Project: Mesos
> Issue Type: Bug

> Affects Versions: 0.17.0
> Environment: Fedora 20 - Linux 3.12.10-300.fc20.x86_64 #1 SMP Thu Feb

> During initial packaging I had turned a blind-eye to some failing tests.
> Upon further investigation there appears to be an issue with how processes
> are reaped on (F20 )
> It appears that there is a status call on the /proc entry of a child process
> before waitpid is called, in my env the entry is gone, and the tests yield
> the following:
> [----------] 3 tests from Reap
> [ RUN ] Reap.NonChildProcess
> libprocess/tests/reap_tests.cpp:84: Failure
> status.get() is NONE
> [ FAILED ] Reap.NonChildProcess (42 ms)
> [ RUN ] Reap.ChildProcess
> libprocess/tests/reap_tests.cpp:123: Failure
> status.get() is NONE
> [ FAILED ] Reap.ChildProcess (31 ms)
> [ RUN ] Reap.TerminatedChildProcess
> libprocess/tests/reap_tests.cpp:150: Failure
> process is NONE
> Process 18856 reaped unexpectedly
> [ FAILED ] Reap.TerminatedChildProcess (3 ms)
> [----------] 3 tests from Reap (76 ms total)
> [----------] 4 tests from Subprocess
> [ RUN ] Subprocess.status
> libprocess/tests/subprocess_tests.cpp:40: Failure
> s.get().status().get() is NONE
> [ FAILED ] Subprocess.status (30 ms)
> [ RUN ] Subprocess.output
> libprocess/tests/subprocess_tests.cpp:129: Failure
> s.get().status().get() is NONE
> [ FAILED ] Subprocess.output (31 ms)
> [ RUN ] Subprocess.input
> libprocess/tests/subprocess_tests.cpp:182: Failure
> s.get().status().get() is NONE
> [ FAILED ] Subprocess.input (31 ms)
> [ RUN ] Subprocess.splice
> libprocess/tests/subprocess_tests.cpp:221: Failure
> s.get().status().get() is NONE
> [ FAILED ] Subprocess.splice (32 ms)
> [----------] 4 tests from Subprocess (124 ms total)
> trace of failure:
> process::ReaperProcess::reap () at reap.cpp:36
> os:process () at linux.hpp:54
> proc:status () at proc.hpp:174
