[issue26839] Python 3.5 running in a virtual machine with Linux kernel 3.17+ can block at startup or on importing the random module on getrandom()

[Colm Buckley]

Colm Buckley added the comment:

Oh; it's not actually hashlib which is calling getrandom(), it's the main runtime - the initialization of the per-process secret hash seed in _PyRandom_Init

Don't know enough about the internal logic here to comment on what the Right Thing is; but I second the suggestion of msg264303. This might just require setting "flags" to GRND_NONBLOCK in py_getrandom() assuming that's portable to other OS.
