According to SUSv2 the corect #define to use here is IOV_MAX, which
unfortunately we don't seem to define anywhere. Steven's Unix
programming book says:
4.3BSD and SVR4 limit iovcnt to 16. 4.3+BSD defines the
constant UIO_MAXIOV, which is currently 1024. The SVID
claims the constant IOV_MAX provides the same Syetem V
limit, but it's not defined in any of the SVR4 headers.
Maybe Garrett or Bruce could comment further on what the correct way
for us to define this is.
