Two questions, which I guess are in Jeff Hill's area of knowledge but 
others may know:

1. Is it possible to run the CA client layer on a vxWorks system which is 
*not* an EPICS IOC?  Would this be an easy thing to do, or is the vxWorks 
client too closely integrated with the server and database code?  At a 
first glance it's not as simple as just loading caLib because that has 
other link dependencies.

2. Is the host client layer thread-safe (I guess this depends on the host 
OS ?) -- i.e. can my applications dedicate a separate thread to run 
ca_pend_event, or even have multiple threads calling other CA routines?  
What would happen if I called ca_pend_io?

Thanks in advance,

- Andrew
