Here, it might be helpful to comment explaining why we are setting --num-callers=350 and --gen-suppressions=all, for future reference

Added README.md file explaining the suppression workflow
Renamed suppression file Added script for extracting suppressions Removed valgrind-python.supp suppresisons

| Setting --num-callers=350 forces the total number of suppressions frames to be below 500 and avoids this error | ||

Might be better to rename ts_re to timestamp_pattern?

If we pass in a suppressions file when running valgrind, and the suppressions file contains a block with a named suppression, in the logs does valgrind print a suppressions block with that name? I'm not sure when this condition would be true

Noticed the suppressions file is quite large: We might need to store this in Git LFS (large file storage) so it doesn't slow down git |
