Terminal freeze / lag with file paths

[bpasero]

I was resolving a conflict for vscode-distro with 500 file paths showing up in the terminal as a result and noticed how typing became very slow. Kudos to @jrieken auto profiling, we have a trace:

Terminal output:

This was caused by xtermjs/xterm.js#4298, it may fixable on the VS Code side though.

Something is not getting disposed, I verified that the number of times each link detector is called increases
