The advice in the HACKING file is still to aim in that direction:


     Although this is a long-term goal, it also would be nice to move CVS
     in the direction of reentrancy.  This reduces the size of the data
     segment and will allow a multi-threaded server if that is desirable.
     It is also useful to write the code so that it can be easily be made
     reentrant later.  For example, if you need to pass data from a
     Parse_Info caller to its callproc, you need a static variable.  But
     use a single pointer so that when Parse_Info is fixed to pass along a
     void * argument, then the code can easily use that argument.

Also, there do some to be some advantages to eventual reentrancy, mostly speed
and memory profile advantages available from using threads instead of separate
processes, I believe.

Are you suggesting that reentrancy no longer be a long-term goal?  Simply that
pratical considerations make a security design like Alexey's more important in
the short term?
