[Caml-list] Re-entrant OCaml

Dear all,

I am currently investigating a proprietary application server with an
embedded functional language. The current implementation of the language
misses several features and one particular interesting path for further
development would be to compile it to OCaml.

There is, however, the caveat of embedding the generated code in the
application server. Right now, (compiled) programs are called directly
from the core (effectively just C-functions) and call a certain API on
the core (again, C-functions). This is possible in OCaml, too, but the
default runtime is not thread-safe. If multiple such calls are made
concurrently, I expect immediate havoc.

Is there any project that provides a re-entrant runtime? In particular,
I would be interested in a version of libasmrun (and the corresponding
compiler) that does not rely on static variables. Instead, the required
data could be passed as an argument to each function.

Is there any such backend currently under development? How are the
chances of mainlining?

regards,

Christoph
