Subject: bug#65720: Guile-Git-managed checkouts grow way too much

Hi,

wolf <wolf@wolfsden.cz> skribis:

‘get-internal-run-time’ returns “units of processor time” used by the
current process (info "(guile) Time").  When shelling out, the process
calls waitpid(2) and does nothing, so naturally its processor time is
close to zero.

‘get-internal-real-time’ should give something closer to elapsed time.
