Description
I am doing data processing and generating many plots with many scripts running in parallel. The scripts use texmanager, and many fail when drawing topng due to below. My plots are large, with many subplots, and the filesystem I'm writing to is slow. Therefore, the hardcoded limit of 50 tries with 0.1 second waits is not appropriate.
Those hardcoded values should be configurable so that the user can change them if needed.

This maybe due to any other process holding thislock. If you are sure no other matplotlib process is running tryremoving these folders and trying again.Unfortunately, the nature of the problem makes it hard to write a minimum code snippet that reproduces it, because it only occurs with big plots when running many processes in parallel.
I'm using Matplotlib 2.0.0rc2 (installed through pip) on Python 3.5.
