Is the trie class threadsafe?

[sbyma]

In particular, the main parse_text method. Is it safe for multiple threads to call parse_text at the same time?

I am using the master branch, and i just fix one multi-thread crash bug for my usage.
My usage is very simple: load the dict once and only one thread do the load work. Then multi-thread will call parse_text() and never call insert(). The bug occurs randomly when calling parse_text(), the callstack stops at construct_failure_states(). My solution is make construct_failure_states() a public member function, and call it in load dict thread after loading.

construct_failure_states

the function name should be "check_construct_failure_states()"
