* The call is probably fast (with the tid in vdso), but dbx intercepts the syscall.
|
|
* 7182047 syscall() has large overhead under dbx on linux
|
|
* One option is to use an assembly call to get the tid.
|
|
* We know how to do this on x86, but not on SPARC.
|
|
* So another option is to do the syscall once and cache the result in thread-local storage.
|
