…pythonGH-119343) Reading a specially prepared small Plist file could cause OOM because file's read(n) preallocates a bytes object for reading the specified amount of data. Now plistlib reads large data by chunks, therefore the upper limit of consumed memory is proportional to the size of the input file.
