tuned

indent broken lines of bindings in do blocks

more line breaks in integral notation

allow line breaks in integral notation

allow line breaks in probability syntax

don't minimize chained facts -- this leads to subtle failures, e.g. if a method succeeds without a chained fact but fails with it

measurability prover: removed app splitting, replaced by more powerful destruction rules

tuned warnings: observe Context_Position.is_visible;

removed unused/non-portable with_tmp_fifo;

discontinued fifo channel, always use portable socket;

do not crash into already running exec, instead join its lazy result in the subsequent step (amending 59f1591a11cb);

more explicit errors;

proper latex;

tuned -- less redundant;

proper Session.save with shutdown, which is relevant to avoid persistent threads;

tuned latex;

merged

always use socket to test performance and stability;

explicit shutdown of scheduler and worker thread farm, assuming Session.shutdown() before saving heap image; discontinued spontaneous thread expiration from TTY age to avoid sporadic Simple_Thread.fork, which is potentially fragile in situations of resource shortage;

tuned;
