pyopenbsd's Issues

pledge('', '') always gets the process killed

I started to add tests in my fork, and I found that a process calling pledge('', '') always gets killed.

$ python3.8 -c "import openbsd; openbsd.pledge('', '')"
Abort trap (core dumped)

I thought that python might be calling some forbidden syscall at the end of the program, so I tried with os._exit:

$ python3.8 -c "import os; import openbsd; openbsd.pledge('', ''); os._exit(0)"
Abort trap (core dumped)

Same issue. On the manual of pledge(2), it is said that _exit(2) is allowed.

A promises value of "" restricts the process to the _exit(2) system call. This can be used for pure computation operating on memory shared with another process.
