The process of passing symbols from the eBPF context to the user space is not trivial. Copying symbol names on each frame processing is avoided as it is not efficient. [Python Symbolization](https://perforator.tech/docs/en/reference/language-support/python/symbolization.md) section describes how python symbols are handled in the eBPF program.
