Long-running yes, blocking, no. There is no magic way to make a blocking
API not-block. So you need to either rewrite from scratch, or use

For example, "send an email and return success or failure" can be
written using non-blocking APIs, since sockets have non-blocking APIs.
Calling a DB-API database adapter's cursor.fetchall() method can not
(unless you want to rewrite the database's wire protocol).
