CHAPTER SIXTEEN MULTIPROCESSING MuPDF has no integrated support for threading - calling itself “thread-agnostic”. While there do exist tricky possibil- ities to still use threading with MuPDF, the baseline threading support. Using in a Python threading environment will lead to blocking effects for the main thread. However, there is the option to use Python’s multiprocessing module in a variety of ways.
