Lately we have gotten many reports of heap corruption. This appears to happen when there is a heavy load using http TPC which uses curl. There have been other people reporting curl memory corruption as well, especially when not resetting options upon handle reuse. See curl/curl#4143

The weird thing is that what this bug report talks about seems apparent in the tpc code where XrdTpcTPC.cc:382 is
//curl_easy_setopt(curl, CURLOPT_BUFFERSIZE, 128*1024);

However, not resetting the buffer size may lead curl to corrupt the heap. Why was this line commented out?
