Thread safety issue

[xiaopengli89]

ferrisetw has a thread safety issue(xiaopengli89/precord#9), I checked the code and the cause of the issue should be here:

https://github.com/n4r1b/ferrisetw/blob/master/src/trace.rs#L99

There definitely could be some thread-safety issues, I'll have a look at it.

Do you have more context? Did you run into bugs/crashes? Is there any debugging log you'd like to share? What makes you think that line is the cause of your issue?

Thanks

Multiple threads modify schemas at the same time(https://github.com/n4r1b/ferrisetw/blob/master/src/schema.rs#L130), resulting in crashes or memory errors.

I'm planning to take care of this in an upcoming release of this crate

Hello. If you're on a hurry, you can have try to use this temporary branch, which resolves the very issue you've pinpointed.
That's a draft of version 1.0, which has breaking changes from the released 0.1.1

There is some extra work to do however regarding possible race conditions between threads where one thread would drop the UserTrace while another is still running a callback. I'll fix this in an upcoming PR as well.

This has been fixed in ferrisetw 1.0
