This reverts commit 038eacfbf4.
It was reported that this change causes a regression when trying
to obtain the screen resolution with `CGDisplayPixelsWide()` or
`CGDisplayPixelsHigh()` after changing the process title.
This is the second time this change had to be reverted due to
regressions and, although third time is allegedly the charm,
leaving well enough alone is the proverb I plan to adhere to...
