[issue8214] Add exception logging function to syslog module

[Eric Smith]

New submission from Eric Smith <eric at trueblade.com>:

Sean Reifschneider proposed [1] adding the ability to log an exception using the syslog module.

My proposed implementation is along the lines of:

def logexceptions(chain=True):
    import sys
    import traceback
    import syslog

    # Should we chain to the existing sys.excepthook?
    current_hook = sys.excepthook if chain else None

    def syslog_exception(etype, evalue, etb):
        if current_hook:
            current_hook(etype, evalue, etb)
        # The result of traceback.format_exception might contain
        # embedded newlines, so we have the nested loops.
        for line in traceback.format_exception(etype, evalue, etb):
            for line in line.rstrip().split('\n'):
                syslog.syslog(line)
    sys.excepthook = syslog_exception

Although it would need to be written in C to work in the existing syslog module, and of course it would call syslog.syslog directly.
