> Some yetus log files are left incomplete, and in these same runs {{tee}} subprocesses are left running and dangling on the ptest server.
> This is because of a bug in the yetus runner velocity template script where we make a redirection of stdout:
> {code}
> ./dev-support/test-patch.sh ${patchFile} ..... 2>&1 | tee ${logFile}
> {code}
> If the yetus output is big enough (>62K) tee will stop writing the log file and is left running even after {{test-patch.sh}} finished successfully. This because we don't make anything consume the stdout and most probably some buffers get full on Linux side.
> We should also make sure that yetus runs(since they are executed parallel to ptest test phase) are not interfering with each other in case they run very long and overlap.
