# Workarounds

# Rename urandom to random

# Handle upward-growing stack
# Some platforms such as emscripten have a stack that grows up. We've rewritten

# With optimizations, register and stack variables might be held in a JavaScript
# local variables, which breaks garbage collection. Indeed, these JavaScript
# variables cannot be marked as root during garbage collection, which means that
# the heap objects they depend on will likely be destroyed. When the Python
# computing resumes, if necessary heap objects have been destroyed, the Python
