Subject: [PATCH 2/3] Invert the sense of psll_linux_clock_ticks.
It is always used to divide some other number, so instead save its
reciprocal. Since division is generally slower than multiplication,
doing one reciprocal and multiplication everywhere else should be
slightly faster.

Subject: [PATCH 3/3] Use safer comparison for process start time.
Comparing two doubles for equality can be troublesome, especially on
32-bit systems (possibly due to 80-bit registers). Checking for some
epsilon is safer.
