Steps to reproduce:

• $filesystem->chmod($directory, 0755, true)

Expected result:

• Changes mode of all files in $directory to 0755, recursively -- but allowing continuation of script.

Actual result:

• Changes mode of all files in $directory to 0755, recursively -- but stops continuation of script.
