Subject: [PATCH] Added volatile into a variable, based on advice from andyhhp
 from SRCF. [22:40] <andyhhp> curl_process_msgs()'s use of "static int slept"
 is dangerous and racy.  an optimising compiler can and probably will do bad
 things [22:45] <ff266> with respect to "static int slept", should i just put
 a volatile in front of it? So "volatile static int slept"? [22:46] <ff266> I
 meant "static volatile int slept;" [22:47] <andyhhp> lets say yes for the
 sake of argument [22:47] <andyhhp> "its complicated" [22:47] <andyhhp> but
 that will broadly do what you want
