However
retrying means issuing another syscall, so additional overhead...
I guess such "best effort" approach would be unusual for a syscall, so
maybe we can keep it as it is now and if such "do not block" mode is needed
we can use flags to implement it later?
Yeah, an explicit opt-in via flags would be an option if that turns out
to be really necessary.
I am fine with keeping it as it is but we do need the non-blocking
option (via flags) to enable userspace to act more aggressively.
