PyExtraSafe is a library that makes it easy to improve your program’s security by selectively
allowing the syscalls it can perform via the Linux kernel’s seccomp facilities.

The python library is a shallow wrapper around [extrasafe](https://docs.rs/extrasafe/0.1.2/extrasafe/index.html).

### Quick Example

```python
from threading import Thread
import pyextrasafe

try:
    thread = Thread(target=print, args=["Hello, world!"])
    thread.start()
    thread.join()
except Exception:
    print("Could not run Thread (should have been able!)")

pyextrasafe.SafetyContext().enable(
    pyextrasafe.BasicCapabilities(),
    pyextrasafe.SystemIO().allow_stdout().allow_stderr(),
).apply_to_all_threads()

try:
    thread = Thread(target=print, args=["Hello, world!"])
    thread.start()
    thread.join()
except Exception:
    print("Could not run Thread (that's good!)")
else:
    raise Exception("Should not have been able to run thread")
```
