Remove parent's env vars from child processes
{code}
I am not sure what JIRA this commit represents (cc [~rkanter] for comment ) .
It seems it should be reverted until further discussion. When the parent
process environment including PATH is not inherited all the utils used without
their absolute path (such as bash above, setsid, etc) stop working. Even if
they worked the previous contract that this test catches is violated: you
should be able to augment the worker's environment variable A for your job by
using the idiom
{code}
A=myPrefix${A}mySuffix
{code}
However, $\{A\} will now be subbed by the empty string.
