There is a sig_atomic_t type. Should we use that one? https://www.gnu.org/software/libc/manual/html_node/Atomic-Types.html "To avoid uncertainty about interrupting access to a variable, you can use a particular data type for which access is always atomic: sig_atomic_t. Reading and writing this data type is guaranteed to happen in a single instruction, so there’s no way for a handler to run “in the middle” of an access."
