oha Potential Memory Leak

[nanqic]

Description:
While running 'oha' continuously, it has been observed that the memory usage keeps increasing over time. Initially, it starts at 2%, but after 6 hours it rises to 16%, and after a day it reaches 50%.

Command executed:
nohup oha -c 500 'http://10.0.10.11/' -z 99h -m HEAD -t 30s --no-tui >>.logs/oha.log &

thanks.

Currently, oha is collecting ALL data of each request.
So memory usage increases proportionally to the number of requests.

It is potentially solved by using a smarter algorithm such as hdrhistogram. But not yet implemented.
