That depends on how long the INSERT statement takes to return. :-) In 
principle, it shouldn't be a big deal.

sql_query_async() is just a wrapper around something very similar to the 
mqueue/rtimer example I gave in the previous post. It's just more 

As far as whether there's a performance hit, that's a complex 
discussion. Any external I/O wait incurs some delay, but whether it's 
significant or whether it's worth doing anything about it is hard to say.

As it happens, I just wrote an article on this topic last night:
