New issue 2226: Excessive heap growth with simple program
https://bitbucket.org/pypy/pypy/issues/2226/excessive-heap-growth-with-simple-program
Ivan Kozik:
I have a program that reads ~50KB-4MB of data from a subprocess every 12
seconds, and after running it for about a month, the pypy process (pypy 4.0.1
on Ubuntu 15.10) uses ~950MB resident memory, while I expect it to be using
much less.
A simplification of that program exhibits the problem in less than a minute:
```
import random
while True:
contents = " " * random.randint(50000, 4000000)
```
I believe pypy is making an erroneous assumption about the need for heap growth.
fijal told me to file this and that "this looks relatively serious".
