Oh,
Just read about Facebook/Percona's version of libmysql that uses non blocking
sockets: https://github.com/webscalesql/webscalesql-5.6
MariaDB also seems to have a non-blocking client library that is likely
compatible (We've used mariadb client with MySQL 5.5 for years for some boring
dependency reasons).
I guess it would be possible to use those directly in libmill coroutine,
provided there is some way to wait on the result being ready for example if
they expose the raw fd and you can use fdwait.
If you get something working let us know!

Hello,
I like libmill a lot. The fact that Martin is behind it is even better.
Question: can libmill be used to fire away several coroutines, where each
coroutine issues (possibly) blocking calls?
For example, say I want to create 4 coroutines, each connecting to a
different MySQL DB, running a query and returning the results (which will
later be aggregated). Could this be done with a single process libmill
program, running 4 coroutines, without any calls to mfork()? What would
happen if the call to mysql_real_connect(), which internally issues socket
calls, were to block?
Cheers,
