High consumption of RAM memory

[J9B10]

Hello.

Thank you for this beautiful program. Congratulations on the brilliant idea.

I'm not an advanced HTML programmer. I only know how to do a "Hello World!".

I used version: vanity-eth-offline.zip / vanity-eth.html

After 4 hours of use it consumed more than 7GB RAM then Google Chrome crashed and issued an error: "Out Of Memory".

This problem happens on any brand of web browser be it on PC or smartphone. On both Windows or Linux systems.

When using this software I saw that my PC crashed with high RAM usage. I also noticed this on my smartphone when android issued a high RAM usage alert.

The high consumption of RAM memory after a few hours of use makes my browser literally crash and stop the whole process.

I'm here to ask you to please try to fix this problem.
