string type,
and strings were mutable (although frequently used as if there were
immutable). Since OCaml-4.02 there is the immutable string and
the mutable bytes type.
The general strategy for switching to the string/bytes scheme is
to replace string everywhere with bytes, and to provide
additional functions taking strings as input or output where it
makes sense. There are exceptions, though, e.g. when the string
acts as a key in a data structure.
The type name "string" also occurs in function names (e.g.
"get_string") and in variant names (e.g. String_case). As we
want to be backward compatible, we keep the old names for functions
on bytes, and mark them as deprecated.

exception EAGAIN_WR
Unix.EAGAIN error but includes whether it was a read or write.
When the read or write is possible, the interrupted function should simply be again called.
These two exceptions are preferred by TLS providers.
