Thanks. Just guessing: maybe wasm32 uses float64 but i686 uses float80. Hence this might go away if flintlib were compiled with `-mfpmath=sse` or similar. We don't do that because supposedly...

Note: sagemath 10.4 in our repo is already patched to support numpy 2.0, but it will need to be rebuilt.

The point of having a os-level interrupt handler is to rollback the process (using longjmp) to a state where the python signal handler can be called. IOW, I don't think...
