[ECOS] interrupts always enabled in scheduler

[Sergei Slobodov]

Hi,

I'm new to this list, sorry if the question has been answered (I did 
search through the archives first, without success).

I'm looking through the sources, trying to determine whether we should 
try to use ecos or port our own kernel from another platform, and there 
is at least one major issue I don't understand. ECOS seems to support 
nested interrupts, yet there is no interrupt enable/disable pair around 
the code that manipulates thread queues, such as Cyg_Thread::resume(), 
which non-atomically changes global scheduler structures. Woudn't it 
cause data corruption if a higher priority interrupt occurs in the 
middle of resume() call?

Please enlighten me!
