[New-bugs-announce] [issue41563] .python_history file causes considerable slowdown

[Denniver]

New submission from Denniver <bitspace at gmx.net>:

The seemingly unlimited growth of the ".python_history"-file seems to cause a massive slowdown when starting or exiting python, the same after running commands.
On one machine python took about 3 minutes to start and I found out that while it is seemingly doing nothing, it was constantly aceesing the ".python_history"-file, which was 130 Mb large. After deleting the file, anything was back to normal.
