Categories from pseudo heap profiles are inferred from two sources:

1. File path that started a task
2. File path that created a file watcher

In both cases file paths are truncated by ExtractCategoryFromTypeName(), which removes file name, and limits number of path components to 3.

So category "net/socket" can refer to any of the 46 .cc files in net/socket/.

In order to increase actionability of pseudo traces we need to preserve as much information as possible.

Step 1: don't truncate file paths.
Step 2: maybe even include line number to disambiguate even more.
