Hi,

I found out that if a document contains multiple identical plots ( exactly same source code to generate the plot), pandoc-plot fail ( in a random way) over a race condition on the created files.

pandoc-plot: plots/pandocplot12097460476205103681.src.html: withFile: resource busy (file is locked).

I work around this by adding some random comment different in each plot code source.

I run across that issue when dealing with automated generated document (Test report) with identical plots ( basic pie chart showing the test results (PASS/FAIL).

I think this could be solve by adding a random part in the calculation of the plot ID. And probably conditioned by an option to not impact performance when not needed.
