Yes.  In particular you can't specify the stack size, and there is no 
way to change this after creation once the native_handle is available.  
See this thread:

Although I can't find it now, I recall also reading a message from 
Howard Hinnant where he said that this had been put to the standards 
committee but had not got anywhere.  I think Howard was suggesting that 
other "interested parties" should put together a proposal in the hope 
that they would have more luck (but this is a while ago now so I may 
not be remembering right).  To me, since I had other problems with the 
std::thread proposal (i.e. their choice of cancellation semantics [*]), 
and because I only care about POSIX, it was simplest just to write my 
own thread class.

[*] If there's anyone else using glibc's pthread cancellation and C++ 
destructors I would always be interested to talk....
