Using threads and poll in nginx module

[klinem2112]

Dear all, 

I run into following problem when writing a module for nginx under Linux. 

Within my module I have to use a library which internally uses multiple
threads (pthreads) as well as poll. 

When using/calling methods of this library in main initialization handler of
my nginx module everything works fine. 

Problem: But when I try to execute same code within other handling methods
then the library is no longer working and method calls that internally use
poll and threads seems to hang forever. 

So my questions are: 

1) Is it possible to use a library in an nginx module that internally uses
poll and multiple threads?
2) If not, is there any approach to use such a library within a nginx
module?

Thanks for your help. 
Best regards Kline
