[Zope-Annce] [Ann] SharedResource

[Dieter Maurer]

Usually, each thread has its own data to minimize interference
and to localize synchonization in the transaction commit.

However, this makes it difficult to control such data from
a single point. E.g. it is very difficult to invalidate
cache entries: while there is no problem for a thread to
invalidate entries in its own cache, it is very difficult
to do the same with the corresponding caches in the other
threads.

'Shared Resource' is a module that manages resources
shared by all threads. Such resources can be controlled
much more easily. A shared resource provides
locking capabilities (via Python's RLock) and performs
automatic locking for function calls.
Access to non-functions is not protected.
