Tests fail when run in parallel

[mgorny]

I can reliably get either integration or connector_http tests to fail when run in parallel, e.g.:

$ ctest -j 9
Test project /home/mgorny/git/libjson-rpc-cpp/_build
    Start 9: all
    Start 6: connector_filedescriptor
    Start 4: connector_http
    Start 7: stubgen
    Start 1: client
    Start 3: common
    Start 8: integration
    Start 5: connector_unixdomainsocket
    Start 2: server
1/9 Test #8: integration ......................***Failed    0.19 sec
2/9 Test #3: common ...........................   Passed    0.32 sec
3/9 Test #7: stubgen ..........................   Passed    0.52 sec
4/9 Test #2: server ...........................   Passed    0.49 sec
5/9 Test #5: connector_unixdomainsocket .......   Passed    0.49 sec
6/9 Test #1: client ...........................   Passed    0.52 sec
7/9 Test #4: connector_http ...................   Passed    2.05 sec
8/9 Test #6: connector_filedescriptor .........   Passed    4.26 sec
9/9 Test #9: all ..............................   Passed    5.18 sec

89% tests passed, 1 tests failed out of 9

Total Test time (real) =   5.18 sec

The following tests FAILED:
	  8 - integration (Failed)
Errors while running CTest
$ ctest -j 9
Test project /home/mgorny/git/libjson-rpc-cpp/_build
    Start 8: integration
    Start 9: all
    Start 6: connector_filedescriptor
    Start 4: connector_http
    Start 7: stubgen
    Start 1: client
    Start 5: connector_unixdomainsocket
    Start 2: server
    Start 3: common
1/9 Test #8: integration ......................   Passed    0.73 sec
2/9 Test #2: server ...........................   Passed    0.71 sec
3/9 Test #7: stubgen ..........................   Passed    0.82 sec
4/9 Test #1: client ...........................   Passed    0.81 sec
5/9 Test #5: connector_unixdomainsocket .......   Passed    0.81 sec
6/9 Test #3: common ...........................   Passed    0.80 sec
7/9 Test #4: connector_http ...................***Failed    1.02 sec
8/9 Test #6: connector_filedescriptor .........   Passed    4.33 sec
9/9 Test #9: all ..............................   Passed    5.56 sec

89% tests passed, 1 tests failed out of 9

Total Test time (real) =   5.56 sec

The following tests FAILED:
	  4 - connector_http (Failed)
Errors while running CTest

Thanks for detecting that. I never tried running them in parallel but I guess by using different ports und filedescriptors it's fixable.
