Please don't use cothread releases 2.4 or 2.5 without applying the following patch:

diff --git a/cothread/catools.py b/cothread/catools.py
index 840acd3..9bd89c8 100644
--- a/cothread/catools.py
+++ b/cothread/catools.py
@@ -741,6 +741,7 @@ def caput_one(pv, value, datatype=None, wait=False, timeout=5, callback=None):
     else:
         # Asynchronous caput, just do it now.
         cadef.ca_array_put(dbrtype, count, channel, dbr_array)
+        _flush_io()
 
     # Return a success code for compatibility with throw=False code.
     return ca_nothing(pv)


As you can see, I've forgotten to call ca_flush_io after asynchronous caput.  I've deleted these releases from the DLS web site (though they'll still remain tagged in git).

I'll make a proper (2.6) release after investigating Guobao's concerns about timestamps.

Note that 2.3 is not subject to this issue as the big change from 2.3 to 2.4 was changing from calling ca_pend_event() to allowing asynchronous callbacks, and ca_pend_event() forces ca_flush_io.
