Subject: [Caml-list] Long running finalizers and global lock

Hi again,

the reference manual states:

 > Note: the finalize, compare, hash, serialize and deserialize
functions attached to custom block
 > descriptors must never trigger a garbage collection. Within these
functions, do not call any of
 > the Caml allocation functions, and do not perform a callback into
Caml code. Do not use
 > CAMLparam to register the parameters to these functions, and do not
use CAMLreturn to return the result.

I have a long running function inse a finalizer is it safe to release
and acquire the runtime lock ?

Best Regards
