+Summary: Deadlock in PageParser
+If XSP starts and gets immediately hit by a lot of requests,
+a deadlock may occur, at least on SMP (hyperthreading too) machines.
+I've tested with SVN head and the 1.1.13 branch on SLES9 (x86_64)
+and on SUSE 9 (x86).
+The deadlock doesn't occur if any page (it's irrelevant which page)
+is compiled by a web browser request before XSP gets hit by a lot
+of requests.
+The deadlock occurs somewhere in the method
+TemplateControlCompiler.CreateControlTree(), but see the attached
+gdb log.
+I was able to fix the problem by puting a lock in PageHandlerFactory
+that lasts only for the first 10 requests, but this is obviously a hack.
