[freetds] Fw: FreeTDS vs Threads

From the FAQ:
Is FreeTDS thread safe?
Different threads may all use separate connections without interfering
with each other. Threads may not share a DBPROCESS or CS_CONNECTION
without controlling access via a mutex.
I took that as a hint that
(a) threads *can* share a DBPROCESS provided Thread 1 cleans up any
cursors (or transactions) before Thread 2 uses it.
(b) A process can keep a pool of DBPROCESSes, and threads can use
different DBPROCESSes in parallel.
Now I have a report of intermittent failures (a SELECT statement
returning FAIL) that smells of a possible thread-related issue.
Can someone confirm that my assumptions are (or should be) safe
and I need to be looking elsewhere for a bug?
