xmlParseFile死锁问题
多个线程同时调用xmlParseFile出现死锁，
gdb调试发现所有的子线程都是下面这样：
#0 0x000000347b20aee9 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0
#1 0x000000347ca9a5ab in xmlRMutexLock () from /usr/lib64/libxml2.so.2
#2 0x000000347ca974ac in ?? () from /usr/lib64/libxml2.so.2

google搜索出有人也出现过，但未果：http://mail.gnome.org/archives/xml/2007-June/msg00110.html
请问有人还遇见过吗？

是不是主线程也用了xmlconfig？
