how can I block all threads for a specific amount of time? (i need to
sleep whole process for testing purposes). i thought of accessing GIL
and sleep for some amount of time, but I don't know how to do this and
whether GIL is recursive.

i have a generator that raises an exception when calling next(),
however if I try to catch the exception and print the traceback i get
only the line where next() was called
while True:
try:
iterator.next()
except StopIteration:
break
except Exception, e:
traceback.print_exc()

supposing that I have a server (an instance of SocketServer()) that
waits for a connection (ie is blocked in accept()) and in another
thread i want to stop the server, how do I do that?

Wrong. What if producer takes a long time to produce an item?
Consumers
will find the queue empty

how is Queue intended to be used? I found the following code in python
manual, but I don't understand how to stop consumers after all items
have been produced. I tried different approaches but all of them
seemed incorrect (race, deadlock or duplicating queue functionality)

how can I catch (globally) exception that were not caught in a try/
catch block in any running thread? i had this weird case that an
exception was raised in one thread, but nothing was displayed/logged.

how do I execute another python script under a different process? I
want the script to be run using the same interpretoer as the one
running current script. I tried using os.execlp but I don't know how
to get the name/path of the interpreter.

my current implemen
does anyone know a nice implementation of callbacks in python? i have
issues mixing named & unamed parameters. i want build a callback over
a function such that some parameters are passed when callback is
created and the rest are passed when the function is called.
example:
callback = Callback(fun
I want to derive a base class, such that some methods are decorated.
The only thing I have in mind is:
class Base(object):
def A(self, x): pass
def B(self, y): pass
class Derived(Base):
@decorator
def A(self, x): Base.A(self, x)
Is this correct approach? How can avoid call to Base.A(...
I'm using python's interpreter's to run various commands (like a
normal shell). However if sources are modified changes are not
reflected so I have to restart interpreter. Is there any way to avoid
restarting this?
example:
import blah
blah.Blah()
# ... blah.Blah() changed
blah.Blah()
# ... new
