Thanks :-) . System has 175MB and 60 seconds timeout as well. I run the 
flask site using gunicorn, the command goes
gunicorn pylive:app --workers=2 --access-logfile 
/path/to/pylive/app_log.log --error-logfile 
/path/to/pylive/error_log.log --log-level debug  --timeout=120 --daemon 
--bind=127.0.0.1:46793 --pid=/path/to/pylive/.pid

Currently total worker space is around 50MB for 2 workers, 175 MB for 
single pypy-sandbox , so 50 + 250MB(300MB), so if server receives more 
than 2 concurrent request, it should be handled by gunicorn(I might be 
wrong). Yes there are chances request will get lost, I am working on 
this area, to separate app and sandbox to different system and introduce 
queuing system, I will be increasing no of workers as well as memory.

I have fixed parsing html tags.

Yes its not security bug since its impossible to write to particular 
location in filesystem and read.

The below code also fails
with open('a.txt', 'w') as f:
     f.write('I am hacker')

with open('a.txt', 'r') as f:
     print f.readlines()
