[moxingwen]

I have a crawl which consume message from Kafka and crawl the web site from this message. When this app run long time ,I found that the process is crash because the memory leak cause by colorama is initialized multiple times.

I have also been troubled with RecursionError due to multiple colorama.init() calls (crawl4ai 0.4.1, colorama 0.4.6).

I hope this pull request #977 will be merged.
