map: subgroup of worker_group;

added worker_group; fork: default to subgroup of worker_group; removed obsolete fork_local; join/get_result: cumulative flattened exceptions; map: subgroup of worker_group;

support for nested groups -- cancellation is propagated to peers and subgroups; added is_canceled; tuned;

added flatten/flatten_list -- supercedes internal plain_exns; represent empty failure as EXCEPTIONS [] instead of Interrupt;

propagate exceptions within future groups; Future.map: inherit group;

less ambitious ML_OPTIONS;

disabled macbroy6 -- hardware repair;

tuned;

tuned tracing; provide spare worker threads to saturate hardware while other workers wait during join;

prefer simultaneous join -- for improved scheduling;

tuned dequeu_towards: try immediate tasks before expensive all_preds;

Display.pretty_thm now requires a proper context;

proper context for Display.pretty_thm etc. or old-style versions Display.pretty_thm_global, Display.pretty_thm_without_context etc.;

moved ProofContext.pretty_thm to Display.pretty_thm etc.; explicit old-style versions Display.pretty_thm_global, Display.pretty_thm_without_context etc.; removed some very old thm print operations;

moved pretty_goals etc. to Display_Goal (required by tracing tacticals); load display.ML after assumption.ML, to accomodate proper contextual theorem display;

removed obsolete CVS Ids;

Proof.future_proof: declare all assumptions as well; Proof.future_proof: removed spurious exception_trace (which might cause crash-by-interrupt); replaced Future.fork_local by Future.fork_pri (again, until group exceptions are propagated properly);

parallel_proofs: more fine-grained control with optional parallel checking of nested Isar proofs;

cancel_proofs: some attempts at reworking group management (based on body promises only);

support for arbitrarity nested future proofs -- replaced crude order by explicit normalization (which might loop for bad dependencies); export promises_of; removed obsolete pending_groups; tuned;

more abstract Future.is_worker; Future.fork_local: inherit from worker (if available);

tuned;

future_result: explicitly impose Variable.sorts_of again;

recovered a version of dequeue_towards (cf. bb7b5a5942c7); join_results: work only towards explicit dependencies -- otherwise could produce dynamic cycle (not recorded in queue);

added join_bodies;

scheduler: tuned tracing (status); join_wait: more robust is_finished check;

added group_id; added status;

synchronized: tuned tracing;

tuned;

tuned prf_subst: use structure Same;
