[plt-scheme] transactions without SQL

I'm fiddling with the webserver,  and I'm thinking of trying a simple
wiki, but was hoping to avoid the 'lost update problem'.  I should
work it out myself and write a little transaction manager, as this
would be a learning experience.  I know most of the time managing this
sort of thing is done by the RDBMS or [in the case of a wiki] a
version control system, but I'd rather look at Scheme code as this is
what I am trying to look concentrate at the moment.

The reason I emailed the list is I thought that this sort of thing
probably already exists in Scheme, and might be fun to look at.

[I'm also curious why the transction 'ACID' properties are not built
into PL's (that I know of).]

Please let me know if you can think of an example that I could take a look at.
