Flamegraph

This is a follow-up to bug 148616, which fixed the performance issue with the FILEOPEN part.

- Open attachment 179594 [details], a POTX template, from bug 148616,
- Save as ODP.

=> Hang, very slow processing. (I haven't waited to the end, it might finish after a while)

Observed using LO 24.8.0.0.alpha0+ (6d5d9eaa61505cebaf3bde4bfc157d8e19fec8de) / Ubuntu.

Attaching flamegraph of a perf recording that went on for a bit, maybe 30 seconds or so.
