TODO: fix CefWebURLRequest memory corruption and restore weakrefs
#
for PyWebRequest object. Right now getting memory corruption
#
when CefRefPtr[CefWebURLRequest] is released after the request
#
is completed. The memory corruption manifests itself with the
#
"Segmentation Fault" error message or the strange "C function
#
name could not be determined in the current C stack frame".
#
See this topic on cython-users group:
#
https://groups.google.com/d/topic/cython-users/FJZwHhqaCSI/discussion
#
After CefWebURLRequest memory corruption is fixed restore weakrefs:
#
1. cdef object g_pyWebRequests = weakref.WeakValueDictionary()
#
2. Add property "cdef object __weakref__" in PyWebRequest
#
When using normal dictionary for g_pyWebRequest then the memory
#
corruption doesn't occur, but the PyWebRequest and CefWebURLRequest
#
objects are never released, thus you have memory leaks, for now
#
there is no other solution. See this topic on the CEF Forum:
#
http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=10710

that's why we need a wrapper for PyWebRequest.
