Thanks for answering. 
Unfortunately no. I definitely tried rethrowing exception. 
And, after thread cancellation, depending on the Linux system used, 
the program either crashed or cancelled thread hung in system part of
the stack. 
Because of that Linux remains the only OS where we do not use pthreads.
