[ECOS] Errno in DSRs

Is it valid to write or read errno in DSR context?
Ie is there are separate errno instance for DSR, or
will the assignment occur to a thread DSR, or a NULL pointer.

The reason for asking is pthreads semaphore funcs eg
sem_trywait set errno, but we call them from DSRs sometimes.

Maybe we shouldn't be using the pthreads version??
