[Pvfs2-developers] About threads

We do use a few threads internally. dbpf uses a thread in dbpf-thread.c.
Job layer also uses threads to drive completions (src/io/job/thread-mgr.c)
(for BMI on client & server, pvfs2-device on client and trove on server)

I also found that when a client performed I/O operations, new threads were

glibc does it internally in its implementation of aio .
