This object schedules the submission of the tasks in an :class:`Flow`.
There are two types of errors that might occur during the execution of the jobs:
#. Python exceptions
#. Abinit Errors.
Python exceptions are easy to detect and are usually due to a bug in abinitio or random errors such as IOError.
The set of Abinit Errors is much much broader. It includes wrong input data, segmentation
faults, problems with the resource manager, etc. Abinitio tries to handle the most common cases
but there's still a lot of room for improvement.
Note, in particular, that `PyFlowScheduler` will shutdown automatically if
#. The number of python exceptions is > MAX_NUM_PYEXC
#. The number of Abinit Errors (i.e. the number of tasks whose status is S_ERROR) is > MAX_NUM_ERRORS
#. The number of jobs launched becomes greater than (SAFETY_RATIO * total_number_of_tasks).
#. The scheduler will send an email to the user (specified by mailto) every REMINDME_S seconds.
If the mail cannot be sent, it will shutdown automatically.
This check prevents the scheduler from being trapped in an infinite loop.

RTP & RTCP: version bits (2 bits) value equals 2

Tried to fake a Stun request and response so that we don't have to relay stun msgs to NDN, but failed. It worked for a time, although will significantly high rate of the STUN message exchanges
We need to use the username exchanged in the sdps for stun it worked for a while but magically stopped working, so now we still send it over NDN

This object schedules the submission of the tasks in a :class:`Flow`.
There are two types of errors that might occur during the execution of the jobs:

Python exceptions are easy to detect and are usually due to a bug in the python code or random errors such as IOError.
The set of errors in the ab-initio is much much broader. It includes wrong input data, segmentation
faults, problems with the resource manager, etc. The flow tries to handle the most common cases
but there's still a lot of room for improvement.
Note, in particular, that `PyFlowScheduler` will shutdown automatically in the following cases:
#. The number of python exceptions is > max_num_pyexcs
#. The number of task errors (i.e. the number of tasks whose status is S_ERROR) is > max_num_abierrs
#. The number of jobs launched becomes greater than (`safety_ratio` * total_number_of_tasks).
#. The scheduler will send an email to the user (specified by `mailto`) every `remindme_s` seconds.
