What is the purpose of this PR / why it is needed?
Previously, symbolizer had a cache of all modules involved in call stack frames. The map of modules was designed by indexing the module path to module info. This could lead to bogus symbolization outcomes if the module is unloaded on the base address that is later recycled to load a new module.
To mitigate this problem, the symbolizer holds a per-process module map.
