Some of the jstests for master/slave do a hard kill (signal 9) as part of testing. This causes problems when MMAP is allocating a file when it is killed. We can now remove this flavor of testing without losing important test coverage.
The tests that still do hard kills are:
repl10.js:doTest(9); // SIGKILL
repl2.js:doTest(9,

{"vv": null, journal: null }

); // SIGKILL
repl3.js:doTest( 9 ); // SIGKILL
repl5.js:doTest(9,

{ journal: null }

); // SIGKILL

The tests that have had killing already removed since 3.0 are:
repl1.js:doTest( 9 ); // SIGKILL
repl6.js:doTest( 9 ); // SIGKILL
repl7.js:doTest(9,

{ journal: null }

); // SIGKILL
