Thanks :), I needed it for the userspace aio_suspend() and lio_listio().

The thread name patch to cygwin_internal() [sic] is for the benefit of 
strace, the forthcoming cygmon, and any other utility that might want to 
display thread names of some other process.  The pthread part of the patch 
does use those functions you mentioned; the cygthread part uses the 
existing cygthread::name() and a new ::setname() I supply.
