Suggestion

Further improvements on #40460:

• Tracing from tsserver
• Post-processing script to handle size & unterminated dumps
• Optimize tracing._ calls (done via tracing?._)
• Using sampling to reduce tracing costs
• Possibly use a proper sampling (worker) thread
  • Filter include/exclude command-line selection (not needed if sampling thread works)
• Adjust expression source locations in post processing script
• Improve UI by embedding tracing as a library (since there are no better visualizers)
• Consolidating data and metadata into a single file
• Enabling streaming gzip?
