Whenever part chunks are written, every fwrite in the write loop will reset the mtime to the current mtime. Only at the end will the touch() operation set the mtime to now + ttl, in the future. However the GC code is expecting that every chunk with mtime < now are old and must be deleted. This causes the GC to sometimes delete part chunks in which the write loop is slow. To fix this, a tolerance value is added in the GC code to allow for more time before a part chunk gets deleted.
