libpyfcgi.IoOut can be use for stdout & stderr for alternate workers too

Syslog seems to block entering in screen copymode... verbose mode drops
messages allowing pyfcgi to continue.

Add missing ./ in front of src/pyfcgi

Add a -l --listen option to set the socket path or address:port
Fix a bug using thread safe functions from libfcgi

Now libtoolize copy missing files
Adds m4 macro directory for aclocal
etc.

This overflow was avoided using the volatile i

Declaring a counter as volatile to avoid GCC opti :/

The problem seems to appear when a worker fails to wait indicate it is idle
by waiting the WSTATE semaphore (maybe when pool handler waited the sem
to check pool's busyness and before the pool handler post it again...)

When running dummy scripts the sem_timedwait was unable to detect that the
pool was busy...

Defining a PYFCGI_STATS_SZ = 15 * 60s = 900

- send buffer formated by stats functions to clients
- close client socket if needed
- allow bind to reuse an address if nobody listen on it

The worker indicate each new request using semaphore
