I was under the impression the kernel would not. IIRC, previous
discussions involving HPUX compatibility suggested the fix go into glibc.

I thought patches had been submitted so pppd would accept both.
I see that it (a) has not and (b) SunOS has EWOULDBLOCK handling
in it's output() handler (see sys-sunos4.c).
