[ECOS] Making driver interruptable

[Samie Hassan Ghauri]

Are the device drivers any different from any functions called by a thread 
currently running? I mean, eg. a thread calls I/O API cyg_io_write() which 
in turn passes the control to device driver routines. If now another thread 
with higher priority becomes runnable, will the execution of driver routines 
be halted to let the higher priority thread run?

In this regard, I see the driver no different from any other functions 
called by the thread. Any comments???
