Hi:

While looking for memory leaks in JCA,
I noticed that simply using R3.14.9/10 fixes part of
the problem because the epicsAtThreadExit() method
in newer EPICS relases is used by JCA to properly detach
CA threads from JNI threads.

But it seems that epicsAtThreadExit actually
adds a new memory leak in src/libCom/misc/epicsExit.c:

static exitPvt * createExitPvt ()
{
    // The exitPvt calloc'ed in here ...
    exitPvt * pep = calloc ( 1, sizeof ( * pep ) );
    if ( pep ) {
        ellInit ( &pep->list );
    }
    return pep;
}

// ... is not free'd in here
static void destroyExitPvt ( exitPvt * pep )
{
    ellFree ( &pep->list );
    // Fix:
    // free (pep)
}

Thanks,
-Kay
