i haven't been able to reproduce this, but the patch below (also in
cvs) may fix. seeing that ssl_io_hook_read sets rc = 0 if SSL_read
returns -1 and SSL_get_error is SSL_ERROR_WANT_READ. ssl_io_input_read
was *always* returning APR_SUCCESS if it got 0 bytes. now it only does so
if SSL_ERROR_WANT_READ was the reason, otherwise returns APR_EOF.
