From "man sendfile" on both OSX and FreeBSD: <<[EINTR] A signal interrupted sendfile() before it could be completed. If specified, the number of bytes successfully sent will be returned in *len.>> Right now we catch EINTR and simply retry. Instead we should only retry is no bytes were sent, else we should return those bytes, similarly to what we do on EAGAIN and EBUSY: https://github.com/python/cpython/blob/2438cdf0e932a341c7613bf4323d06b91ae9f1f1/Modules/posixmodule.c#L8907-L8917
