Delay is not the point, you start all independent tasks and then dependent tasks for each are arranged to wait for all their precedents. Now, only one process can wait for each running process, so if many processed need to know what is done, a log file, directory of marker files or other database can track progress, and you can check progress in a loop every N seconds. You could write a supervisor that knows the prereqs of every new process. You could put the prereqs in a SQL db, same db as the completions, so you can query what is not run and no prereq is missing, and launch any found. You would be writing ControlM or Tivoli TWS and such.

NAME
Dist::Zilla::Prereqs - the prerequisites of a Dist::Zilla distribution VERSION
version 4.300020 DESCRIPTION
Dist::Zilla::Prereqs is a subcomponent of Dist::Zilla. The "prereqs" attribute on your Dist::Zilla object is a Dist::Zilla::Prereqs object, and is responsible for keeping track of the distribution's prerequisites. In fact, a Dist::Zilla::Prereqs object is just a thin layer over a CPAN::Meta::Prereqs object, stored in the "cpan_meta_prereqs" attribute. Almost everything this object does is proxied to the CPAN::Meta::Prereqs object, so you should really read how that works. Dist::Zilla::Prereqs proxies the following methods to the CPAN::Meta::Prereqs object: o finalize o is_finalized o requirements_for o as_string_hash METHODS
register_prereqs $prereqs->register_prereqs(%prereqs); $prereqs->register_prereqs(\%arg, %prereqs); This method adds new minimums to the prereqs object. If a hashref is the first arg, it may have entries for "phase" and "type" to indicate what kind of prereqs are being registered. (For more information on phase and type, see CPAN::Meta::Spec.) For example, you might say: $prereqs->register_prereqs( { phase => 'test', type => 'recommends' }, 'Test::Foo' => '1.23', 'XML::YZZY' => '2.01', ); If not given, phase and type default to runtime and requires, respectively.
