Description
While one process/thread is writing a pyramid file, another file may access it for reading as opposed to getting a MissingPyramidException. Read access will need to block (with a time limit?) until writing is finished.
Note: for this to work, we will need to close the writer even if the main thread continues reading the file to allow other threads to read.
