Along with\u000athe new --usdt-file-activation feature in bpftrace\u000a( https://github.com/iovisor/bpftrace/pull/1317 ), bpftrace can\u000apotentially hold onto many dozens of USDT:Context instances, causing\u000amemory issues.\u000a\u000aWhile reducing the amount of memory USDT::Context uses is one option,\u000awe can potentially side step it by allowing the usdt semaphore count to\u000abe set independently.
