why should LocalIo be safe?

If there's mutable state, why should sharing between tasks work?

td lib...
Apr 07 23:05:16 <DanC_> looking into random leads me to fs_open which leads to "
LocalIo is unsafe and should not be. rust-lang#11053" https://github.com/mozilla/rust/iss
ues/11053
Apr 07 23:06:37 <DanC_> funny thing is: if the IoFactory authority were passed a
round explicitly, rust-lang#11053 wouldn't be an issue
Apr 07 23:07:05 <DanC_> they have event loops and such, but the whole standard l
ibrary emphasizes synchronous IO APIs

This is overtaken by the removal of the rust runtime, I'm pretty sure.
